TPS53313 provides a 5-V or 12-V synchronous buck converter that integrates two N-Channel
MOSFETs. Due to low RDS(on) and TI proprietary SmoothPWM skip mode of operation, it optimizes the efficiency at light-load
condition without compromising the output voltage ripple.
The TPS53313 features programmable (from 250 kHz to 1.5 MHz) switching frequency with
selectable skip mode or forced CCM mode operation. The device provides prebiased startup,
soft-stop, integrated bootstrap switch, power good function, and EN/input UVLO protection. It
supports input voltages from 4.5 V to 16 V and no extra bias voltage is needed. The output voltage
is adjustable from 0.6 V up to 0.7 × VIN.
The TPS53313 is available in a 4 mm × 4 mm, 24-pin VQFN package (Green RoHs compliant and
Pb free) and operates from –40°C to 85°C.
