SC4806MLTRT

Overview

The SC4806MLTRT is a double-ended, high-speed PWM controller from Semtech. It operates within a -40°C to +105°C temperature range and utilizes a 12-MLPQ package. The device supports programmable frequencies up to 1MHz and features dual push-pull output drive stages. Key electrical characteristics include a 90µA starting current and pulse-by-pulse current limiting for both voltage and current modes.

Feature Summary

Configurable for current mode or voltage mode operation
Integrated control circuitry for isolated applications with secondary side error amplifier support
Dual output drive stages in push-pull configuration
Programmable external soft start and slope compensation

Applications

Push-pull converter topologies
Half bridge converter designs
Full bridge converter systems
Isolated VRMs (Voltage Regulator Modules)

Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest documentation to ensure authenticity. Confirm that the 12-MLPQ footprint matches your PCB design requirements. Check for any RoHS compliance certificates if required by your manufacturing standards. Ensure the operating temperature range meets your environmental specifications.

Selection Notes

Select this component when designing isolated power supplies requiring flexible control modes. It is suitable for applications needing minimum space due to its high integration. Consider the programmable frequency limits and input voltage ranges during the initial schematic design phase to ensure compatibility with the chosen transformer and passive components.

Part Context

This part belongs to the SC4806 series of double-ended PWM controllers. It is designed for high-efficiency isolated power conversion. The series is optimized for telecom, networking, and industrial power supplies where compact size and performance are critical.
