LIA135S

Overview

The LIA135S is a low voltage optically isolated error amplifier manufactured by IXYS Integrated Circuits Division. It integrates a precision programmable shunt reference, an error amplifier, and an optocoupler into a single package. The device operates with an input voltage range of 1.6V to 10V over the temperature range of -40°C to +85°C. It features a voltage reference of 1.299V with ±1% accuracy across the operating temperature range. The integrated optocoupler provides a current transfer ratio (CTR) from 500% to 2000%. Common mode transient immunity is specified at 5V/ns. The component utilizes an 8-pin surface mount package.

Feature Summary

Integrates a precision voltage reference, error amplifier, and optocoupler in a single package
Operates down to a minimum input voltage of 1.6V
Provides high common mode transient immunity for noise reduction
Features industry-leading dynamic range due to bias current isolation

Applications

Low Voltage Power Supply Feedback
Isolated Power Supply Feedback
AC-to-DC Power Supplies
DC-to-DC Converters

Procurement Notes

Verify that the specific part number suffix 'S' corresponds to the 8-pin surface mount tube packaging configuration as defined in the ordering information. Confirm compliance with UL Recognized Component File # E76270 and CSA Certified Component Certificate # 1305490 requirements for your intended application environment. Ensure handling procedures adhere to MSL 1 ratings and JESD-625 ESD sensitivity standards during assembly.

Selection Notes

Select the LIA135S when designing isolated power supplies requiring operation at very low input voltages starting from 1.6V. This component is suitable for applications needing simplified frequency compensation and high noise immunity. Consider this part for designs where minimizing external components for feedback loops is a priority. Verify that the required common mode transient immunity meets the 5V/ns specification for your system's switching environment.

Part Context

The LIA135S belongs to the LIA135/LIA136 family of low voltage optically isolated error amplifiers. These devices function as functional equivalents to a 431 type precision shunt regulator combined with an optocoupler. The series is designed to sample power supply outputs, generate error signals, and transmit them across isolation barriers. The S suffix specifically denotes the surface mount variant within this product line.
