Introduction
The TPS40000 and the TPS40001 are voltage-mode, synchronous buck PWM controllers that utilize TI’s
proprietary Predictive Gate Drive
technology to wring maximum efficiency from step-down converters. This
controller family 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 utilizing either the TPS40000 or TPS40001 controller.
A schematic for the board is shown in Figure 1. The list of material is provided in section 7 of this User’s Guide.
