Product Summary

The FAN5235QSCX is a high efficiency and high precision DC/DC controller for notebook converters. Utilization of both input and output voltage feedback in a current-mode control allows for fast and stable loop response over a wide range of input and output voltage variations. The two main regulators switch out of phase to minimize input ripple current.

Parametrics

Absolute maximum ratings: (1)VIN: -0.3 to 27 V; (2)SW, ISEN Pins,SDWN Pin: -0.3 to 27 V; (3)CPUMP, HSD Pins: -0.3 to 33 V; (4)SDN, VFB, V_always pins: -0.3 to 6.5 V; (5)CPUMP to SW pins, and all other pins: -0.3 to 6.5 V.
