Filtering Noise Reduction DC/DC Converters achieve their rated ripple noise specifications using external input output capacitors specified Performance/ Functional Specifications table. critical applications, input/output noise further reduced installing additional external caps. Input capacitors should selected bulk capacitance, high rms-ripple-current ratings. Output capacitors should selected appropriate frequency response. caps should have appropriate voltage ratings mounted close converters possible. most effective combination external capacitors will function your particular load layout conditions. Applications Engineers will pleased recommend potential solutions discuss possibility modifying device's internal filtering meet your specific requirements.

Input Overvoltage/Undervoltage Shutdown Start-Up Threshold Under normal start-up conditions, devices will begin regulate until ramping-up input voltage exceeds Start-Up Threshold Voltage (35V "D48" models). Once operating, devices will turn until input voltage drops below Undervoltage Shutdown limit (32V "D48" models). Subsequent re-start will occur until input brought back Start-Up Threshold. This built-in hysteresis prevents unstable on/off situations from occurring single voltage. Input voltages exceeding input overvoltage shutdown specification listed Performance/Functional Specifications will cause device shutdown. built-in hysteresis typical "D24" models, typical "D48" models) will allow converter restart until input voltage sufficiently reduced.

Sync Function (Optional feature)
critical applications employing multiple switching DC/DC converters, necessary intentionally synchronize switching selected converters. Series offers optional Sync function ("S" suffix) place On/Off Control Sync will self-configure either slave master, depending circuit application.
LTAG
Models
Sync detects appropriate input signal, will configure itself slave; signal detected, will generate master Sync pulses. Synchronization converters requires that master switching frequency exceed slave frequency minimum 60kHz. start each DC/DC converter switching cycle, internally generated 200-450ns pulse will present Sync pin. however, unit receives external Sync pulse, DC/DC converter's switching cycle will terminated cycle initiated. Since master frequency higher than slave switching frequency, slave cycles always terminated prematurely, thereby never allowing internal Synch pulses generated. external signal's rising edge initiates slave Sync process. External signals must adhere min./ max. limits stated Performance/Functional Specifications. Operating series DC/DC converters higher switching frequencies external Sync function will result slight degradation efficiency. Contact DATEL further information. Output Overvoltage Protection Each voltage output Series converter independently monitored auxiliary winding output inductor. output voltage should rise level which could damaging load circuitry (see Performance/Functional Specifications limits), overvoltage circuitry will power down controller latch DC/DC converter. device must restarted powering cycling VIN. Current Limiting When output current demands exceed maximum output current rating 107% 133%, DC/DC converter will into current limiting mode. this condition output voltage decreases proportionately output current increases, thereby maintaining somewhat constant power dissipation-referred Power Limiting (see Figure load approaches short circuit, output current will continue increase until reaches rated Short Circuit Current limit.
Short Circuit Condition described under "Current Limiting," when Series DC/DC converter output subjected short circuit condition, output current will remain Short Circuit Current limit. this state there negligible power dissipated load. Therefore, most input power dissipated within converter, causing internal temperature increase. this condition persists, Thermal Shutdown will activate shutdown DC/DC converter. When internal temperature sufficiently decreased, converter will self-start. Thermal Shutdown Series equipped with Thermal Shutdown circuitry. internal temperature DC/DC converter rises above designed operating temperature, precision temperature sensor will power down unit. When internal temperature decreases below threshold temperature sensor unit will self-start. Input Reverse-Polarity Protection Upon applying reverse-polarity voltage DC/DC converter, internal diode will forward biased draw excessive current from power source. Therefore, required that input current limited either appropriately rated input fuse current limited power source. Heat Sinks Series DATEL offers standard heat sinks that mounted half-brick package extend converter's operating temperature range. Along with standard 2.3" 2.4" 0.5" (HS-CP) heat sink, DATEL designed low-profile heat sink height-restricted applications. This heat sink (HS-CPLP2) designed with radiant fins that extend 0.51" beyond either side 2.4" dimension package. convenience this design that finned extensions protrude only 0.31" below surface DC/DC converter, allowing components with profile height less than 0.215" mounted board below heat sink. Therefore, while surface area low-profile heat sink measures 2.3" 3.5", real estate unaffected. optimum thermal performance natural convection application, low-profile heat sink should mounted with fins vertically oriented. Both models shipped with 0.009" sellf-adhesive thermal mounting screws.
