FEATURES

DESCRIPTION

•

Minimum External Parts Count

•

Includes Accurate Output Current Monitor with

Programmable Clamp Voltage

The TPS51513 is a single-phase synchronous buck

controller with integrated gate drivers. Advanced

control features such as the D-CAP+™ architecture

and OSR™ overshoot reduction provide fast transient

response, low output capacitance and high efficiency.

The TPS51513 supports a wide range of IC V_CORE

applications with an integrated 3-bit DAC. It also

provides a full complement of signal I/O including a

sleep mode control (SLP), two power good signals

(PGOOD and PG), and an analog current monitor

(IMON). Logic inputs are compatible with either 1-V

or 3.3-V logic levels. V_COREslew rates are controlled

with one resistor. In addition, the TPS51513 includes

high-current FET gate drivers with an integrated P/N

junction diode to drive N-channel FETs with low

switching loss. The TPS51513 is available in the

5 mm × 5 mm, 32-pin QFN package and operates

between –10°C and 100°C.
