FUNCTIONAL DESCRIPTION
OVERVIEW DCV01 offers unregulated output power with typical efficiency 85%. This achieved through highly integrated packaging technology implementation custom power stage control circuit design utilizes advanced BiCMOS/DMOS process. Separate primary secondary transformer windings give good isolation barrier capacitance. POWER STAGE This uses push-pull, center-tapped topology switching 400kHz (divide from 800kHz oscillator). OSCILLATOR WATCHDOG onboard 800kHz oscillator generates switching frequency divide circuit. oscillator synchronized other DCV01 circuits external source, used minimize system noise. watchdog circuit checks operation oscillator circuit. oscillator stopped pulling SYNCIN LOW. output pins will tri-stated. This will occur 2µs. THERMAL SHUTDOWN DCV01 protected thermal shutdown circuit. on-chip temperature exceeds 150°C, device will shut down. Once temperature falls below 150°C, normal operation will resume. SYNCHRONIZATION event that more than DC/DC converter needed onboard, beat frequencies other electrical interference generated. This small variations switching frequencies between DC/DC converters. DCV01 overcomes this allowing devices synchronized another. eight devices synchronized connecting SYNCIN pins together, taking care minimize capacitance tracking. Stray capacitance 3pF) will have effect reducing
switching frequency, even stopping oscillator circuit. synchronized devices used, should noted that, start devices will draw maximum current simultaneously. This cause input voltage should below minimum input voltage (4.5V), devices start 2.2µF capacitor should connected close input pins. more than eight devices synchronized, recommended that SYNCIN pins driven external device. Details contained separate applications bulletin (AB-153). CONSTRUCTION DCV01's basic construction same standard ICs. There substrate within molded package. DCV01 constructed using rectifier diodes, wound magnetic toroid leadframe. there solder within package, DCV01 does require special assembly processing. This results isolated DC/DC converter with inherently high reliability.
ADDITIONAL FUNCTIONS
DISABLE/ENABLE DCV01 disabled enabled driving SYNC using open drain CMOS gate. SYNCIN pulled low, DCV01 will disabled. disable time depends upon external loading; internal disable function implemented 2µs. Removal pull down will cause DCV01 enabled. Capacitive loading SYNCIN should minimized order prevent reduction oscillator frequency. DECOUPLING Ripple Reduction high switching frequency 400kHz allows simple filtering. reduce ripple, recommended that least capacitor used VOUT. Dual outputs should both decoupled 2.2µF capacitor input versions, 0.47µF DCV01 versions recommended.

Connecting DCV01 Series Multiple DCV01 isolated DC/DC converters connected series provide nonstandard voltage rails. This possible utilizing floating outputs provided DCV01's galvanic isolation. Connect positive VOUT from DCV01 negative VOUT (0V) another (see Figure SYNCIN pins tied together, self-synchronization feature DCV01 will prevent beat frequencies voltage rails. SYNCIN feature DCV01 allows easy series connection without external filtering, minimizing cost. outputs dual output DCV01 versions also connected series provide times magnitude VOUT shown Figure example, dual DCV01 could connected provide rail. Connecting DCV01 Parallel output power from DCV01 sufficient, possible parallel outputs multiple DCV01s, shown Figure Again, SYNCIN feature allows easy synchronization prevent power-rail beat frequencies additional filtering cost. LAYOUT Ripple Noise Careful consideration should given layout order that best results obtained.
DCV01 switching power supply such place high peak current demands input supply. order avoid supply falling momentarily during fast switching pulses ground power planes should used track power input DCV01. this possible then supplies must connected star formation with tracks made wide possible. SYNCIN being used then tracking between device SYNCIN pins should short avoid stray capacitance. SYNCIN being used advisable place guard ring, (connected input ground) around this avoid noise pick output should taken from device using ground power planes, this will ensure minimum losses. good quality capacitor placed close practicable across input will reduce reflected ripple ensure smooth start good quality capacitor placed close practicable across rectifier output terminal output ground will give best ripple noise performance. THERMAL MANAGEMENT high power density this device advisable provide ground planes input output.
