The ISL6522BCBZ from Intersil is a Buck and Synchronous Rectifier Pulse-Width Modulator (PWM) Controller. It is optimized for high-performance microprocessor applications and designed to drive two N-Channel MOSFETs in a synchronous rectified buck topology.
This controller integrates essential control, output adjustment, monitoring, and protection functions into a single package. It offers precise output voltage regulation down to 0.8V with a maximum tolerance of ±1% over temperature and line voltage variations. The device utilizes a simple, single feedback loop, voltage-mode control with fast transient response, featuring a 200kHz free-running triangle-wave oscillator adjustable from 50kHz to over 1MHz.
The ISL6522BCBZ operates from a 10.8V to 13.2V input and supports a maximum duty cycle of 100%. It includes features like Enable, Frequency Control, Phase Control, and Soft Start. The controller protects against overcurrent conditions by inhibiting PWM operation, monitoring current via the MOSFETs' rDS(ON) to eliminate the need for a separate current sensing resistor.
Packaged in a 14-SOIC (0.154", 3.90mm Width) format, the ISL6522BCBZ is designed for surface mount applications. It operates within a temperature range of 0°C to 70°C (TA) and is RoHS3 Compliant with an MSL of 1 Unlimited.
