Overview
The LT1524J is a voltage-mode pulse width modulation (PWM) switching controller manufactured by Analog Devices Inc. It operates within an input voltage range of 8 V to 40 V, with a nominal input of 20 V. The device supports a maximum switching frequency of 300 kHz and features a 0.1 A output drive capability. Packaged in a 16-lead ceramic dual in-line package (CDIP), it functions as a complete PWM control solution including oscillator, error amplifier, and comparator stages.
Feature Summary
- Voltage-mode PWM control architecture for DC-DC switching applications
- Integrated oscillator, error amplifier, and high-current output drivers
- Compatible with SG1524/LM1524 devices for direct replacement
Applications
- Switching power supply converters
- Motor speed control systems
- Offline power converter designs
Procurement Notes
Verify the specific manufacturer source, as the LT1524J designation may originate from Linear Technology or Analog Devices Inc. Confirm the package type matches the required CDIP specification rather than standard plastic DIP. Ensure compliance with RoHS directives if applicable, as historical data indicates some variants may not be compliant. Cross-reference pinouts with official datasheets to prevent integration errors during procurement.
Selection Notes
Select the LT1524J for applications requiring robust voltage-mode PWM control with wide input voltage tolerance. It is suitable for designs needing compatibility with legacy SG1524/LM1524 circuits. Consider the CDIP package for environments requiring hermetic sealing or high thermal stability. Evaluate the 300 kHz maximum frequency against system noise and efficiency requirements.
Part Context
The LT1524J belongs to the family of precision PWM controllers designed for industrial and automotive power management. Originally developed by Linear Technology, now part of Analog Devices Inc., these components are known for high reliability and precise reference voltage tolerances. They serve as foundational elements in various regulated power conversion topologies.
Replacement Considerations
The LT1524J is officially documented as interchangeable with the SG1524 and LM1524 devices. When substituting, verify that the alternative component meets the same electrical specifications and pinout configuration to ensure seamless integration without circuit redesign.
