Dual output regulator has 2–MHz switching

Dual output regulator has 2–MHz switching

The A4402 dual output regulator IC combines a 2% constant on-time buck regulator and a 2% linear regulator to provide dual output voltages suited for microcontroller or DSP-based applications. It includes an adjustable soft-start timer, and is capable of operating at frequencies up to 2 MHz. The regulator targets industrial, consumer and office automation markets.

Protection features for the regulator include under-voltage lockout and thermal shutdown, and overcurrent protection. It’s watchdog timer monitors the state of a microcontroller, DSP, and has a power-on reset function with adjustable delay. The device is provided in a 16–pin TSSOP package, with exposed pad for enhanced thermal dissipation. ($1.23 ea/1,000 — available now.)
