ISL6843IBZ-T Integrated Circuit Chip 2MHz Flyback Buck Boost Converter

ISL6843IBZ-T Boost Flyback Regulator Positive Isolation Capable Output Step-Up DC-DC Controller IC

The ISL6840, ISL6841, ISL6842, ISL6843, and ISL6844 (ISL684x) family of adjustable frequency, low power, Pulse-Width Modulating (PWM) current mode 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.

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.

Features

• 1A MOSFET gate driver

• 60µA start-up current, 100µA maximum

• 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

• 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

• Tight tolerance current limit threshold

• Pb-free available (RoHS compliant)

Applications

• Telecom and datacom power

• Wireless base station power

• File server power

• Industrial power systems

• PC power supplies

• Isolated buck and flyback regulators

• Boost regulators
