www.ti.com . SLUS864 – MAY 2009 SYNCHRONOUS BUCK CONTROLLER WITH HIGH-CURRENT GATE DRIVER
Check for Samples :TPS51113 TPS51163 FEATURES DESCRIPTION The TPS51113 and TPS51163 are cost-optimized,
feature rich, single-channel synchronous-buck
controllers that operates from a single 4.5-V to 13.2-V
supply and can convert an input voltage as low as
1.5 V. 1 Flexible Power Rails: 5 V to 12 V
Reference: 800 mV В± 0.8%
Voltage Mode Control
Support Pre-biased Startup
Programmable Overcurrent Protection with
Low-Side RDS(on) Current Sensing
Fixed 300-kHz (TPS51113) and 600-kHz
(TPS51163) Switching Frequency
UV/OV Protections and Power Good Indicator
Internal Soft-start
Integrated High-Current Drivers Powered by
VDD
10-Pin 3 Г— 3 SON Package The controller implements voltage mode control with
a fixed 300-kHz (TPS51113) and 600-kHz
(TPS51163) switching frequency. The overcurrent
(OC) protection employs the low-side RDS(on) current
sensing and has user-programmable threshold. The …
