Product Summary

The isl6520cb-t is a single synchronous buck pulse-width modulation (PWM) controller. The isl6520cb-t 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 isl6520cb-t integrates the control, output adjustment, monitoring and protection functions into a single 8-pin package. Applications are (1)Power Supplies for Microprocessors: PCs, Embedded Controllers; (2)Subsystem Power Supplies: PCI/AGP/GTL+ Buses, ACPI Power Control; (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)5V-Input DC/DC Regulators; (9)Low-Voltage Distributed Power Supplies.

Parametrics

isl6520cb-t absolute maximum ratings: (1)Supply Voltage, VCC: +6.0V; (2)Absolute Boot Voltage, VBOOT: +15.0V; (3)Upper Driver Supply Voltage, VBOOT - VPHASE: +6.0V; (4)Input, Output or I/O Voltage: GND -0.3V to VCC +0.3V; (5)Supply Voltage, VCC: +5V ±10%; (6)Ambient Temperature Range: 0°C to 70°C; (7)Junction Temperature Range: -40°C to 125°C.

Features

isl6520cb-t features: (1)Operates from +5V Input; (2)0.8V to VIN Output Range; (3)Drives N-Channel MOSFETs; (4)Simple Single-Loop Control Design: Voltage-Mode PWM Control; (5)Fast Transient Response: High-Bandwidth Error Amplifier, Full 0% to 100% Duty Cycle; (6)Lossless, Programmable Over-Current Protection: Uses Upper MOSFETs rDS(on); (7)Small Converter Size: 300kHz Fixed Frequency Oscillator, Internal Soft Start, 8 Ld SOIC or 16Ld 4x4mm QFN.
