General Description

The LTC®3421 is a high efficiency, current mode, fixed frequency, step-up DC/DC converter with true output disconnect and inrush current limiting.

The device includes a 0.10Ω N‑channel MOSFET switch and a 0.14Ω P-channel synchronous rectifier.

This product has the ability to simply program the output voltage, switching frequency, current limit, soft-start, Burst Mode threshold and loop compensation with external passive components.
