4A STEP-DOWN SWITCHING REGULATOR WITH SYNCHRONOUS RECTIFICATION

The L5988D is a synchronous step down monolithic power Switching Regulator capable of delivering up to 4A. The input voltage CAN range from 2.9V to 18V. Thanks to the very short minimum ON time, the device is able to manage extremely low duty cycles, allowing very low output voltages. Requiring a minimum set of external components, the device includes an internal 400 KHz switching frequency Oscillator that CAN be externally adjusted up to 1MHz. The Regulator CAN provide 100% duty-cycle. A multifunction pin allows to enable-disable the sink mode current capability after soft-start, to enable-disable the latch mode for the OVP and to set the UVLO threshold for the 3.3V BUS and 12V BUS. The current limit CAN be externally adjusted to fit the application requirements. The current is sensed during both the on-time and the off-time and so the protection is effective with both very low or very high duty-cycle and/or with high switching frequency. The HTSSOP16 package with exposed pad allows reducing the R to 40C/ thJA By STMicroelectronics
