STBLW35 Datasheet Ultra-low Power And Wide Input Range Buck-boost Converter

Manufacturer: STMicroelectronics

Overview: STBLW35 Datasheet Ultra-low power and wide input range buck-boost converter Product status link STBLW35 Product.

General 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.

The IC shows very low power losses either in active or disable mode and provides an average output current between 33 mA to 70 mA, suitable to guarantee load minimum current constraints or to faster charge a battery.

Key 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.
