Controller IC Chip - MOSFET ISL6520 BCBZ chip for laptop - Ολοκληρωμένο τσιπ φορητού υπολογιστή (Κωδ.1-CHIP0524) Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6520 makes simple work out of implementing a complete control and protection scheme for a DC/DC stepdown converter. Designed to drive N-channel MOSFETs in a synchronous buck topology, the ISL6520 integrates the control, output adjustment, monitoring and protection functions into a single 8-pin package.The ISL6520 provides 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. A fixed frequency oscillator reduces design complexity, while balancing typical application cost and efficiency.The error amplifier features a 15MHz gain-bandwidth product and 8V/μs slew rate which enables high converter bandwidth for fast transient performance.
