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.
