LIA135 / LIA136

Low Voltage Optically Isolated

Error Amplifiers

INTEGRATED

IRCUITS

IVISION

Features

Description

• Low Input Voltage of 1.6V over temperature

• Precision reference, error amplifier, and optocoupler

in a single package

• Voltage Reference: 1.299V ±0.5% @ 25°C

LIA135: ±1% @ -40°C to +85°C

LIA136: ±1.5% @ -40°C to +110°C

• LIA136: Reduced dark current at high temperature

• Common Mode Transient Immunity:

LIA135: 5V/ns

The LIA135 and LIA136 are low voltage optically

isolated error amplifiers with a precision

programmable shunt reference combined into a single

package capable of operating down to 1.6V. The

optocoupler portion of the LIA135 / LIA136 comprises

an infrared LED that is optically coupled to an NPN

phototransistor providing a current transfer ratio from

500% to 2000%. Ensuring low voltage performance,

the input voltage range of 1.6V to 10V is guaranteed

over the operational temperature range.

LIA136: 20V/ns

• Simplified frequency compensation

• CTR 500% to 2000%

The combination of features in the LIA135 / LIA136

are optimal for use in isolated AC-to-DC power

supplies and DC-to-DC converters. The bias current

for the shunt regulator does not pass through the LED,

which eliminates bias-related optical current, giving

the user the industry’s largest dynamic range (1000:1).

• Lowest optical offset current (I vs. V

)

LED

Applications

• Low Voltage Power Supply Feedback

• Isolated Power Supply Feedback

• AC-to DC Power Supplies

These devices are available in DIP and surface mount

(SMT) packages.

• DC-to-DC Converters

Approvals

• UL Recognized Component: File # E76270

• CSA Certified Component: Certificate # 1305490
