3 Description

The TPS560200 is an 17-V, 500-mA, low-Iq, adaptive

on-time D-CAP2 mode synchronous monolithic buck

converter with integrated MOSFETs in easy-to-use 5-

pin SOT-23 package.

The TPS560200 lets system designers complete the

suite of various end-equipment power bus regulators

with a cost-effective, low component count and low

standby current solution. The main control loop for

the device uses the D-CAP2 mode control that

provides a fast transient response with no external

compensation components. The adaptive on-time

control supports seamless transition between PWM

mode at higher load conditions and advanced Eco-

Mode operation at light loads.

The TPS560200 also has a proprietary circuit that

enables the device to adopt to both low equivalent

series resistance (ESR) output capacitors, such as

POSCAP or SP-CAP, and ultra-low ESR ceramic

capacitors. The device operates from 4.5-V to 17-V

VIN input. The output voltage can be programmed

between 0.8 V and 6.5 V. The device also features a

fixed 2-ms soft-start time. The device is available in

the 5-pin SOT-23 package.
