Design TPS53311
SLUSA41B – JUNE 2010 – REVISED SEPTEMBER 2016 TPS53311 3-A Step-Down Regulator With Integrated Switcher
1 Features 3 Description The TPS53311 provides a fully integrated 3-V to 5-V
VIN integrated synchronous FET converter solution
with 16 total components, in 200 mm2 of PCB area.
Due to the low RDS(on) and TI Proprietary
SmoothPWMв„ў skip mode of operation, it enables
95.5% peak efficiency, and over 90% efficiency at
loads as light as 100 mA. It requires only two 22-ВµF
ceramic output capacitors for a power-dense, 3-A
solution. 1 95.5% Maximum Efficiency
Continuous 3-A Output Current
Supports All MLCC Output Capacitor
SmoothPWMв„ў Auto-Skip Eco-modeв„ў for LightLoad Efficiency
Voltage Mode Control
Supports Master-Slave Interleaved Operation
Synchronization up to В±20% of Nominal …
