TPPM0115 TPPM0115 SWITCH MODE SYNCHRONOUS BUCK CONTROLLER SLVS371 SLVS371 MARCH 2001 D D D D D D DC-DC Synchronous Buck Controller Internal Oscillator Frequency, 400 kHz (Typ) Output Voltage, 1 V to 2.5 V ±2% Power Good Function (PWRGD) Input Voltage, 12 V ±5% Load Current Capability, 10 A (Max) description The TPPM0115 TPPM0115 is a synchronous buck controller capable of driving two external power FETs 180° out of phase. The device requires a minimum of external standard filter components and switching FETs to regulate the desired output voltage. This is achieved with an internal oscillator frequency of 400 kHz (typical). In the event the set output is in an over-voltage condition due to a system fault, the drive to the lower FET turns on to correct the fault. There is a small delay between switching one FET ON while the other FET is switching OFF to prevent cross conduction. The TPPM0115 TPPM0115 is capable of driving loads up to 10 A with minimal ripple on the output (
