TPS40007EVM-001
概述
The TPS40007 is a voltage-mode, synchronous buck PWM controller that uses TI's proprietary Predictive Gate Drive™ technology to wring maximum efficiency from step-down converters. This controller provides a bootstrap circuit to allow the use of an N-channel MOSFET as the topside buck switch to reduce conduction losses and increase silicon device utilization. Predictive Gate Drive™ technology controls the delay from main switch turn-off to synchronous rectifier turn-on and also the delay from rectifier turn-off to main switch turn-on.This allows minimization of the losses in the MOSFET body diodes, both conduction and reverse recovery. This design note provides details on a buck converter that converts an input of 3 V to 5 V down to a 2.5 V output level using the TPS40007 controller.
特性
The specification for this board is as follows:
- VIN = 3.3 V to 5 V
- VOUT = 2.5 V ±3%
- IOUT = 0 A to 10 A
- Efficiency = > 95% with VIN = 3.3 V, ILOAD = 4 A
- Output voltage ripple < 2% VOUT
- Power semiconductor devices: Each MOSFET is a single SO-8 package
