STW4141 - Single Coil Dual Output Step Down DC/DC Converter

General Description

The STw4141 is a single coil dual output synchronous step down DC/DC converter that requires only four standard external components.

It operates at a fixed 900 kHz switching frequency in PWM mode.

The device can operate in PFM mode to maintain high efficiency over the full range of output currents.

Key Features

  • Single coil dual output switching converter for digital core supply & digital I/Os supply.
  • Digital I/O supply:VOUT1 @ 200 mA.
  • CPU CORE supply:VOUT2 @ 400 mA Wide range of fixed output voltage configurations available High efficiency synchronous step down converter with up to 92 % for the entire device Size and cost optimized.
