SLVSCN5A – JUNE 2014 – REVISED OCTOBER 2014 TPS65262-1, 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 TPS65262-1 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-V, 9-V, 12-V, 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,
buck3 (buck2 and buck3 run in phase) minimizes the
input filter requirements. At light load, the device …
