General Description

The SC190 is a synchronous step-down converter with integrated power devices and an integrated front-end LDO to minimize input supply ripple.

Output voltage is programmable using two control bits, eliminating the need for feedback resistors tied to the output.

The device is offered in four distinct variants with each variant providing four fixed output voltage options to choose from.

Key Features

  • Features.
  • Less than 1mV Supply Ripple.
  • Output Voltage Regulated by Either the Switching.
  • Regulator or Linear Regulator Dynamic Handover Between Linear and Switching Regulator for Maximum Efficiency 2.7V to 5.5V Input Range 300mA Guaranteed Output Current Fixed Frequency 1MHz Operation or 750kHz to 1.5MHz Clocked Operation No Schottky Diode Required Up to 95% Efficiency (VIN=BP) Over-current Protection Over-voltage Protection Over-temperature Protection Soft Start M.
