4.5V to 17V Input, 500mA Synchronous Step-Down Converter with Advanced Eco-Mode™

The TPS560200-Q1 is an 17V,

500mA, low-Iq, adaptive on-time D-CAP2 control scheme mode

synchronous monolithic buck converter with integrated

MOSFETs in easy-to-use 8-pin MSOP

package.

The TPS560200-Q1 lets system

designers complete the suite of various end-equipment power

bus regulators with a cost-effective, low component count

and low standby current design. The main control loop for

the device uses the D-CAP2 sontrol scheme 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-Q1 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 4.5V to 17V VIN input.

The output voltage can be programmed between 0.8V and 6.5V.

The device also features a fixed 2ms soft-start time. The

device is available in the 8-pin MSOP package.
