STBLW35 - Ultra-low power and wide input range buck-boost converter

Description

The STBLW35 is an ultra-low power and high-efficiency buck-boost DC-DC converter which can work as boost or buck-boost according to the selected hardware configuration.

When in buck-boost the DC-DC can seamlessly switch between the two working modes depending on operating conditions.

Features

  • Seamless transition from Buck-Boost to Boost and vice versa working mode.
  • Up to 70 mA output current.
  • Four fully integrated MOSFETs.
  • Enable pin.
  • 2.6 V to 5.3 V trimmable overvoltage level (± 1% accuracy).
  • 2.2 V to 3.6 V trimmable undervoltage level (± 1% accuracy).
  • Two fully independent LDOs (1.8 V and 3.3 V output).
  • Enable/disable LDO control pins.
  • Load disconnect function at first switch-on.
  • Embedded pas.
