DESCRIPTION

The TPS54350 is a medium output current synchronous
buck PWM converter with an integrated high side
MOSFET and a gate driver for an optional low side
external MOSFET. Features include a high performance
voltage error amplifier that enables maximum
performance under transient conditions and flexibility in
choosing the output filter inductors and capacitors. The
TPS54350 has an under-voltage-lockout circuit to prevent
start-up until the input voltage reaches 4.5 V; an internal
slow-start circuit to limit in-rush currents; and a power good
output to indicate valid output conditions. The
synchronization feature is configurable as either an input
or an output for easy 180° out of phase synchronization.
The TPS54350 device is available in a thermally
enhanced 16-pin TSSOP (PWP) PowerPAD package.
TI provides evaluation modules and the SWIFT Designer
software tool to aid in quickly achieving high-performance
power supply designs to meet aggressive equipment
development cycles.
