TSM1013AIST

Overview

The TSM1013AIST is a highly integrated constant voltage and constant current controller designed for switch-mode power supply applications. It integrates one voltage reference with two operational amplifiers to provide precise control in battery chargers and adapters. The device operates within a DC supply voltage range of 4.5V to 28V and supports an operating temperature range of 0°C to 105°C. It features a fixed output voltage reference of 2.5V with 0.5% precision, ensuring high accuracy. The component is housed in a MiniSO-8 package.

Feature Summary

Integrates a fixed 2.5V voltage reference and two transconductance operational amplifiers for combined voltage and current regulation
Features a current sink output stage that enables ORing functionality for simultaneous voltage and current limiting
Provides easy compensation through accessible external components at the operational amplifier outputs and inputs

Applications

Battery Chargers
Adapters

Procurement Notes

Verify the specific suffix 'IST' against official STMicroelectronics documentation to confirm the exact package type (MiniSO-8) and tape & reel packaging configuration. Ensure the 0.5% voltage precision variant matches the design requirements. Cross-reference the datasheet revision date to confirm electrical characteristics remain unchanged.

Selection Notes

Select this component for flyback converter designs requiring secondary-side CV/CC control. Consider the internal zener clamp at 28V when designing auxiliary power supplies. Evaluate the need for primary-side current limitation during startup conditions where Vcc may be insufficient. Verify thermal resistance values for the MiniSO-8 package under expected load conditions.

Part Context

The TSM1013 series serves as a specialized solution for SMPS applications needing accurate secondary-side regulation. It simplifies design by integrating essential control loops into a single chip. The A-grade variant offers tighter voltage reference tolerance compared to standard versions. This integration reduces the external component count required for adapter and charger implementations.
