3 Description
The TPS65320-Q1 device is a combination of a 40-V,
3.2-A, DC-DC step-down converter and a low-dropout
(LDO) regulator. The DC-DC step-down converter,
referred to as the buck regulator, has an integrated
high-side MOSFET. The LDO regulator also has an
integrated MOSFET and a low-input supply current of
28-μA (typical) in a no-load condition.
