Description

The AIC2857F is a synchronous step-down regulator with an integrated Power MOSFET. It achieves 2A continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-bycycle current limiting and thermal shutdown.
Adjustable soft-start reduces the stress on the input source and the output overshoot at turnon.
In shutdown mode, the regulator draws 1μA or less of supply current.

 

APPLICATIONS

1. Networking Systems such as Modems & Routers
2. Distributed Power Systems
3. Pre-Regulator for Linear Regulators.
4. Set-top Box

Description

The PAL012A is an AB class audio power amplifier, packaged in Flexiwatt 25 and designed for high end car radio applications. Based on a fully complementary PNP/NPN configuration, the amplifier allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced boundary components count allows very compact sets.
