DESCRIPTION
Supports All MLCC Output Capacitor
The TPS53310 provides a fully integrated 3-V to 5-V
SmoothPWM Auto-Skip Eco-mode for
VIN integrated synchronous FET converter solution
Light-Load Efficiency
with 16 total components, in 200 mm2 of PCB area.
Voltage Mode Control
Due
to
the
low
RDS(on) and TI's proprietary
SmoothPWM Skip mode of operation, it enables

95.5% peak efficiency, and over 90% efficiency at
Synchronization up to ±20% of Nominal
loads as light as 100 mA. It requires only two 22-F
Frequency
ceramic output capacitors for a power dense 3-A
Conversion Voltage Range Between 2.9 V and
solution.
