TPS53624
www.ti.com SLUSB66 – MARCH 2013 Dual Phase, D-CAP+™, Eco-mode™ Step-Down Controller with 8-Bit DAC
Check for Samples: TPS53624 FEATURES DESCRIPTION The TPS53624 is a dual-phase step down controller
with integrated gate drivers. The PCNT pin enables
operation in dual or single-phase mode to optimize
efficiency depending on the load requirements.
Advanced control features such as D-CAP+в„ў
architecture and OSR provides fast transient
response with low output capacitance. The DAC
supports VID-on-the-fly to optimize the output voltage
to the operating state of the system to reduce
quiescent power. The auto-skip feature of the
TPS53624 optimizes light-load efficiency in single
phase operation. System management features
include adjustable thermal monitor input and output
(THRM, THAL), output current monitoring (IMON),
and complimentary power good signals (PG and
PGD). Adjustable control of the output voltage slew
rate and voltage positioning are provided. In addition,
the TPS53624 includes two high-current FET gate
drivers to drive high and low side N-channel FETs
with exceptionally high speed and low switching loss.
All logic input and output pins have flexible LV input …
