SC4810BITSTRT

Overview

The SC4810BITSTRT is a high-performance current mode PWM controller manufactured by Semtech Corporation. It features complementary outputs and a programmable delay, designed for isolated DC-DC and off-line switching power supplies. The device operates with a maximum switching frequency of 1100 kHz and supports an input voltage range from 6.95 V to 16 V. Packaged in a TSSOP-10 format, it integrates line voltage monitoring, supply UVLO, and low start-up current capabilities.

Feature Summary

• Integrates complementary output drivers with programmable delay functionality
• Employs current mode control architecture for precise regulation
• Includes built-in line voltage monitoring and supply under-voltage lockout

Applications

• Isolated DC-DC converter designs
• Off-line switching power supply systems
• Telecom equipment power stages

Procurement Notes

Verify the specific suffix BITSTRT against official Semtech documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperature ranges and lead-free compliance standards before integration into final hardware designs.

Selection Notes

Select this component when complementary drive signals are required within a compact footprint. The integrated programmable delay allows for optimized timing adjustments without external circuitry. Evaluate thermal performance requirements relative to the TSSOP-10 package constraints for the target application environment.

Part Context

This part belongs to the SC4809 series of primary side current mode controllers. It shares core control logic with variants like the SC4809CIMSTR but adds complementary output capability. The series targets efficient power conversion solutions requiring minimal external component counts.

Replacement Considerations

Direct substitutes include other SC4810B variants such as SC4810BIMLTRT or SC4810BITSTRT with differing packaging options. Cross-reference pinouts and electrical characteristics carefully when considering alternative manufacturers' current mode PWM controllers.
