ISL6843IBZ-T Boost Flyback Regulator Positive Isolation Capable
Output Step-Up DC-DC Controller ICThe 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 Specification of ISL6843IBZ-T Mfr | Renesas Electronics America Inc | Output Type | | Function | Step-Up, Step-Up/Step-Down | Output Configuration | Positive, Isolation Capable | Topology | | Number of Outputs | | Output Phases | | Voltage - Supply (Vcc/Vdd) | | Frequency - Switching | | Duty Cycle (Max) | | Synchronous Rectifier | | Clock Sync | | Control Features | Current Limit, Frequency Control | Operating Temperature | | Mounting Type | | Package / Case | 8-SOIC (0.154", 3.90mm Width) | Supplier Device Package | |
