The ISL6526AIR from Intersil is a single synchronous buck Pulse-Width Modulation (PWM) controller. It is designed to drive N-Channel MOSFETs in a synchronous buck topology, integrating control, output adjustment, monitoring, and protection functions into a single package.
This controller provides a simple, single feedback loop, voltage-mode control with fast transient response. The output voltage can be precisely regulated to as low as 0.8V, with a maximum tolerance of ±1.5% over temperature and line voltage variations. It operates from a 3.3V to 5V input and supports a 0.8V to VIN output range. The fixed frequency oscillator operates at 600kHz, balancing application cost and efficiency.
The error amplifier features a 15MHz gain-bandwidth product and 6V/µs slew rate, enabling high converter bandwidth for fast transient performance. The resulting PWM duty cycles range from 0% to 100%. Protection from overcurrent conditions is provided by monitoring the rDS(ON) of the upper MOSFET, simplifying implementation and improving efficiency by eliminating the need for a current sense resistor.
The ISL6526AIR is available in a 16-lead QFN package (5x5) with an exposed pad, suitable for surface mounting. It is designed for applications such as power supplies for microprocessors, subsystem power supplies, and memory supplies.
