DESCRIPTION
The TPS5435x 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. The TPS5435x
has an under-voltage-lockout circuit to prevent start-up
until the input voltage reaches a preset value; 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 TPS5435x devices are 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.
