TSM1013IST

Overview

The TSM1013IST is a highly integrated constant voltage and constant current controller designed for switch-mode power supply applications. It integrates a fixed 2.5V voltage reference, two operational amplifiers, and a current sink output stage within an SO-8 package. The device operates with a DC supply voltage range of 4.5V to 28V and supports an operating temperature range of 0°C to 105°C. It provides precise voltage regulation and current limiting functions suitable for battery chargers and adapters.

Feature Summary

Integrates a fixed 2.5V voltage reference with high precision
Features two transconductance operational amplifiers for independent control loops
Includes a current sink output stage for optocoupler activation
Supports easy compensation via accessible input and output pins

Applications

Adapters
Battery Chargers

Procurement Notes

Verify the specific suffix 'S' indicates MiniSO packaging available in Tape & Reel format. Confirm the 'I' designation corresponds to the standard 1% voltage precision variant rather than the 'AI' 0.5% version. Ensure the component meets RoHS compliance standards as specified by STMicroelectronics for this active part number.

Selection Notes

Select this component for flyback converter designs requiring secondary side CV/CC control. Evaluate the need for primary PWM module current limitation during startup conditions where Vcc may be insufficient. Consider external resistor networks for setting voltage thresholds and current limits based on the internal 2.5V reference.

Part Context

This part belongs to the TSM1013 family of power supply support circuits manufactured by STMicroelectronics. It serves as a dedicated controller for managing charging profiles in portable electronics. The integration of dual op-amps and a reference reduces external component count compared to discrete solutions.
