SLVSCD3B – DECEMBER 2013 – REVISED MAY 2014 TPS6526x 4.5V to 18V Input Voltage, 3A/2A/2A Output Current
Triple Synchronous Step-Down Converter
1 Features 3 Description The TPS65261, TPS65261-1 is a monolithic triple
synchronous step-down (buck) converter with
3A/2A/2A output currents. A wide 4.5V to 18V input
supply voltage range encompasses the most
intermediate bus voltages operating off 5V, 9V, 12V
or 15V power bus. The converter, with constant
frequency peak current mode, is designed to simplify
its application while giving designers options to
optimize the system according to targeted
applications. The switching frequency of the
converters can be adjusted from 250kHz to 2MHz
with an external resistor. The 180В° out-of-phase
operation between Buck1 and Buck2, 3 (Buck2 and 3
run in phase) minimizes the input filter requirements. 1 Operating Input Supply Voltage Range
