Wide Input Voltage Range Controllers from Intersil

Intersil announced a new family of Triple Sync Buck PWM and LDO Controller. The digital enable features on the ISL9440, ISL9440A and ISL9441 controllers can also be logic-driven for sequencing to avoid using additional chips, saving cost and board space.

ISL9440 and ISL9440A feature an "Early Warning" VIN detection feature that allows 5.5 microseconds for the system to perform functions like writing key registers to memory before the system loses power completely.

The ISL9440, ISL9440A and ISL9441 are designed to be extremely flexible, operating in a wide input voltage range of 4.5V to 24V, and they offer an independent "digital enable" feature that allows designers to save power and board space.
