Improved Industry Standard Single-Ended Current Mode PWM Controller

The ISL6840, ISL6841, ISL6842, ISL6843, and

ISL6844 (ISL684x) family of adjustable frequency, low

power, Pulse-Width Modulating (PWM) current mode

Features

• 1A MOSFET gate driver

• 60µA start-up current, 100µA maximum

controllers is designed for a wide range of power

conversion applications including boost, flyback, and

isolated output configurations. Peak current mode

control effectively handles power transients and

provides inherent overcurrent protection.

• 25ns propagation delay current sense to output

• Fast transient response with peak current mode

control

• Adjustable switching frequency to 2MHz

• 20ns rise and fall times with 1nF output load

This advanced BiCMOS design is pin-compatible with

the industry standard 384x family of controllers and

offers significantly improved performance. Features

include low operating current, 60µA start-up current,

adjustable operating frequency to 2MHz, and high

peak current drive capability with 20ns rise and fall

times.

• Trimmed timing capacitor discharge current for

accurate deadtime/maximum duty cycle control

• High bandwidth error amplifier

• Tight tolerance voltage reference over line, load,

and temperature
