LT4430
Secondary-Side
Opto-Coupler Driver
Features Description 600mV Reference (1.25% Over Temperature)
nn Wide Input Supply Range: 3V to 20V
nn Overshoot Control Function Prevents Output
Overshoot on Start-Up and Short-Circuit Recovery
nn High Bandwidth Error Amplifier Permits Simple Loop
Frequency Compensation
nn Ground-Referenced Opto-Coupler Drive
nn 10mA Opto-Coupler Drive with Current Limiting
nn Low Profile (1mm) ThinSOTTM Package The LTВ®4430 drives the opto-coupler that crosses the galvanic barrier in an isolated power supply. The IC contains
a precision-trimmed reference, a high bandwidth error
amplifier, an inverting gain of 6 stage to drive the optocoupler and unique overshoot control circuitry. nn Applications
48V Input Isolated DC/DC Converters
Isolated Telecommunication Power Systems
nn Distributed Power Step-Down Converters
nn Offline Isolated Power Supplies
nn Industrial Control Systems
nn Automotive and Heavy Equipment
