LTC3785 Datasheet No Rsense Buck-boost Controller

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC®3785 is a high power synchronous buck-boost controller that drives all N-channel power MOSFETs from input voltages above, below and equal to the output voltage.

With an input range of 2.7V to 10V, the LTC3785 is well suited for a wide variety of single or dual cell Li-Ion or multicell alkaline/NiMH applications.

The operating frequency can be programmed from 100kHz to 1MHz.
