Design TPS56528
SLVSBV3B – APRIL 2013 – REVISED NOVEMBER 2016 TPS56528 4.5-V to 18-V Input, 5-A Synchronous Step-Down Converter
With Advanced Eco-Modeв„ў
1 Features 3 Description The TPS56528 device is an adaptive on-time
D-CAP2в„ў mode synchronous buck converter. The
TPS56528 enables system designers to complete the
suite of various end-equipment power bus regulators
with a cost-effective, low component count, low
standby current solution. The main control loop for
the TPS56528 uses the D-CAP2в„ў 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 EcoModeв„ў operation at light loads. Advanced EcoModeв„ў allows the TPS56528 to maintain high
efficiency during lighter load conditions. The
TPS56528 also has a proprietary circuit that enables
the device to adopt to both low equivalent series …
