FN9016.6

Single Synchronous Buck Pulse-Width

Modulation (PWM) Controller

Features

• Operates from +5V Input

The ISL6520A 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 ISL6520A

integrates the control, output adjustment, monitoring and

protection functions into a single 8 Lead package.

• 0.8V to V Output Range

- 0.8V Internal Reference

- ±1.5% Over Line Voltage and Temperature

• Drives N-Channel MOSFETs

• Simple Single-Loop Control Design

- Voltage-Mode PWM Control

The ISL6520A 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.

• Fast Transient Response

- High-Bandwidth Error Amplifier

- Full 0% to 100% Duty Cycle

• Lossless, Programmable Overcurrent Protection

- Uses Upper MOSFET’s r

DS(ON)

The error amplifier features a 15MHz gain-bandwidth

product and 8V/ms slew rate which enables high converter

bandwidth for fast transient performance. The resulting

PWM duty cycles range from 0% to 100%.

• Small Converter Size

- 300kHz Fixed Frequency Oscillator

- Internal Soft-Start

- 8 Ld SOIC or 16 Ld 4mmx4mm QFN

Protection from overcurrent conditions is provided by

• QFN Package:

of the upper MOSFET to inhibit PWM

- Compliant to JEDEC PUB95 MO-220 QFN - Quad Flat

operation appropriately. This approach simplifies the

implementation and improves efficiency by eliminating the

need for a current sense resistor.

- Near Chip Scale Package footprint, which improves

PCB efficiency and has a thinner profile
