ISL78223 Product details

Description

PIN NUMBER 1 2 3 4 5 6 7 8 9 10 PIN NAME VREF VERR CTBUF RTD RESDEL CT FB RAMP CS IOUT DESCRIPTION The 5V reference voltage output with 3% tolerance over line, load, and operating temperature.Bypass to GND with a 0.1µF to 2.2µF low ESR capacitor.The control voltage input to the inverting input of the PWM comparator.The output of an external error amplifier (EA) is

Features

complemented PWM outputs for Synchronous Rectifier (SR) control. The complemented outputs can be dynamically advanced or delayed relative to the PWM outputs using an external control voltage. This advanced BiCMOS design features precision deadtime and resonant delay control and an oscillator adjustable to 2MHz operating frequency. Additionally, Multi-Pulse Suppression ensures alternating output pulses at low duty cycles where pulse skipping may occur. The ISL78223 is rated for the automotive tem.
