3 Description
The TPS560200-Q1 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 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 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-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 4.5-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 8-pin MSOP package.
