The ISL6522CRZ-TK from Renesas Electronics Corporation is a Pulse-Width Modulator (PWM) controller designed for DC-DC converters, specifically optimized for high-performance microprocessor applications. It operates in a synchronous rectified buck topology, driving two N-Channel MOSFETs.
This controller integrates essential functions including control, output adjustment, monitoring, and protection. It offers precise output voltage regulation with a 0.8V internal reference and a tolerance of ±1% over temperature and line voltage variations. The device utilizes a simple, single feedback loop, voltage-mode control with fast transient response, enabled by a high-bandwidth error amplifier.
The ISL6522CRZ-TK features a 200kHz free-running oscillator, programmable from 50kHz to over 1MHz, and supports a full 0-100% duty ratio. Overcurrent protection is provided by monitoring the rDS(ON) of the upper MOSFET, eliminating the need for a separate current sensing resistor. The controller can source and sink current, contributing to a smaller converter size.
Packaged in a 16-lead QFN (5x5mm) with an exposed pad, it is suitable for surface mounting. The operating temperature range is 0°C to 70°C (TA). This controller is designed for applications such as power supplies for microprocessors and high-power DC-DC regulators.
