ISL65261B

The ISL65261B is one member of the ISL65261 family which is designed as the single synchronous buck pulse-width modulation (PWM) controller that provides simple, single feedback loop, voltage mode control with fast transient response. And this device can be used in (1)power supplies for microprocess-ors: PCs and embedded controllers; (2)subsystem power supplies: PCI/AGP/GTL+ Buses, ACPI power control and DDR SDRAM bus termination supply; (3)cable modems, set top boxes, and DSL modems; (4)DSP and core communications processor supplies; (5)memory supplies; (6)personal computer peripherals; (7)industrial power supplies; (8)3.3V-input DC-DC regulators; (9)low-voltage distributed power supplies.

Features of the ISL65261B are:(1)Operates from 3.3V to 5V Input;(2)Output Range 0.8V to VIN: 0.8V Internal Reference and ±1.5% Over Load, Line Voltage and Temperature;(3)Drives N-Channel MOSFETs;(4)Simple Single-Loop Control Design: Voltage-Mode PWM Control;(5)Fast Transient Response: High-Bandwidth Error Amplifier and Full 0% to 100% Duty Cycle;(6)Lossless, Programmable Overcurrent Protection;(7)Converter can Source and Sink Current;(8)Internal Soft-Start.

The absolute maximum ratings of the ISL65261B can be summarized as:(1)Supply Voltage: +7 V;(2)Absolute Boot Voltage: +15.0 V;(3)Upper Driver Supply Voltage: +6.0 V;(4)Input, Output or I/O Voltage: GND -0.3V to VCC +0.3V;(5)ESD Classification: class 2.
