3 Description

The TPS56524x is simple, easy-to-use, high power

density, high efficiency synchronous buck converter.

The device supports input voltage ranging from 3 V to

16 V and up to 5-A continuous current with a SOT-563

package.

The TPS56524x uses D-CAP3 topology to provide

a fast transient response and support low-ESR

output capacitors with no requirement for external

compensation. It has two grounds, GND and AGND,

which should be connected together for optimal

thermal performance. AGND also provides a good

load and line regulation. The device can support up

to 98 duty operation.

The TPS565242 operates in Eco-mode, which

maintains high efficiency during light loading. The

TPS565247 operates in FCCM mode, which keeps

the same frequency and lower output ripple during

all load conditions. It integrates complete protection

through OVP, OCP, UVLO, OTP, and UVP with

hiccup. The device is available in 1.6-mm × 1.6-

mm SOT-563 package and has an optimized pinout

for easy PCB layout. The junction temperature is

specified from –40°C to 125°C.
