Texas Instruments TPS560200

Description

The TPS560200 is an 17V, 500mA, low Iq, adaptive on-time D-CAP2 mode synchronous monolithic buck converter with integrated MOSFETs in easy-to-use 5-pin SOT23 package.

The TPS560200 enables system designers to 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 SOT23 package.
