Synchronous Buck Regulator provides efficiencies to 95%.
Available in a 20-pin 4 x 3 mm MLFÃ-® package, MIC22400 features programmable operating frequency from 800 kHz to 4 MHz and is suited for powering systems from 3.3 and 5 V supply rails. Built-in sequencing, tracking, and ramp control capabilities enable all power-up sequencing and tracking protocols. Along with internal compensation scheme and adjustable output down to 0.7 V, IC has...

Featuring selectable IF bandwidth for 300-450 MHz operation, QwikRadioÃ-® MICRF218 ASK/OOK Receiver can accommodate 2 reference crystals with use of external switch. It includes fully integrated IF section with built-in image rejection. Wide IF bandwidth can be chosen for backward compatibility with older transmitters that are LC-based. Able to escape from jamming source and migrate to...

Operating from 1.7-5.5 V input, soft start Models MIC94064/5 offer output voltage turn-on time of 115 Ã-µs and typical RDS On of 77 mW. Level shift circuitry enables each unit to be driven by 1.5 V logic level. With operating current of 2 Ã-µA and shutdown current of less than 1 Ã-µA, battery time is extended. Model MIC94065 includes active load discharge circuit that insures...
