LM34936 - Synchronous 4-Switch Buck-Boost Controller

Description

The LM34936 is a synchronous four-switch buckboost DC/DC controller capable of regulating the output voltage at, above, or below the input voltage.

The LM34936 operates over a wide input voltage range of 4.2 V to 30 V (42-V absolute maximum) to support a variety of applications.

Features

  • Single inductor buck-boost controller for step-up/ step-down DC/DC conversion.
  • Wide VIN: 4.2 V (2.5 V with bias) to 30 V (42-V maximum).
  • Flexible VOUT: 0.8 V to 30 V.
  • VOUT short protection.
  • High efficiency buck-boost transition.
  • Adjustable switching frequency.
  • Optional frequency sync and dithering.
  • Integrated 2-A MOSFET gate drivers.
  • Cycle-by-cycle current limit and optional hiccup.
  • Optional input or outpu.
