SLVSD87A – DECEMBER 2015 – REVISED DECEMBER 2015 TPS65262-2 4.5-to 18-V Input Voltage, 3-A/1-A/1-A Output Current Triple Synchronous
Step-Down Converter With Dual Adjustable 350-mA/150-mA LDOs
1 Features 3 Description The TPS65262-2 is a monolithic triple synchronous
step-down (buck) converter with 3-A/1-A/1-A output
current. A wide 4.5-to 18-V input supply voltage
range encompasses the most intermediate bus
voltage operating off 5-, 9-, 12-, or 15-V 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 device
operates at 600-kHz fixed switching frequency. The
loop compensations for buck 2 and buck3 have been
integrated for less external components. The 180В°
out-of-phase operation between buck1 and buck2, 3
(buck2 and buck3 run in phase) minimizes the input
filter requirements. 1 Operating Input Voltage Range: 4.5 to 18 V …
