Texas Instruments  TPS560200QDGKRQ1

The TPS560200-Q1 is an 17-V, 500-mA, low-Iq, adaptiveon-time D-CAP2 mode synchronous monolithic buck converter with integrated MOSFETs in easy-to-use8-pin MSOP package.

The TPS560200-Q1 lets system designers complete the suiteof various end-equipment power bus regulators with a cost-effective, low component count and lowstandby current solution. The main control loop for the device uses the D-CAP2 mode control thatprovides a fast transient response with no external compensation components. The adaptive on-timecontrol supports seamless transition between PWM mode at higher load conditions and advancedEco-Mode operation at light loads.

The TPS560200-Q1 also has a proprietary circuit thatenables the device to adopt to both low equivalent series resistance (ESR) output capacitors, suchas POSCAP or SP-CAP, and ultra-low ESR ceramic capacitors. The device operates from 4.5-V to 17-VVIN input. The output voltage can be programmed between 0.8 V and 6.5 V. The device also features afixed 2-ms soft-start time. The device is available in the 8-pin MSOP package.
