Overview
The SG2525AP013TR is a voltage mode PWM controller manufactured by STMicroelectronics, designed for switching power supply applications. It operates within an input voltage range of 8V to 35V and supports a switching frequency from 100Hz to 400kHz. The device features two output channels capable of sourcing or sinking up to 500mA, housed in a 16-SOIC surface-mount package. Key electrical parameters include a maximum duty cycle of 49%, a built-in 5.1V reference trimmed to ±1%, and an operating temperature range of -25°C to +85°C.
Feature Summary
- Integrated soft-start circuitry requiring only an external timing capacitor
- Built-in undervoltage lockout with hysteresis for jitter-free operation
- Pulse-by-pulse shutdown capability via the PWM latch
- Separate oscillator sync terminal for clock synchronization
Applications
- DC-DC buck converter designs
- Push-pull topology power supplies
- Boost/buck-boost converter systems
- General-purpose switching power supply controllers
Procurement Notes
Verify that the ordering suffix '013TR' corresponds to the tape-and-reel packaging format as specified in official documentation. Confirm the component status is active and check for any specific environmental compliance certifications such as RoHS requirements relevant to the target market before finalizing procurement orders.
Selection Notes
Select this component when a voltage mode control strategy is required for dual-output or push-pull topologies. Ensure the application demands a switching frequency within the 100Hz to 400kHz range and requires the specific 16-SOIC footprint. Evaluate thermal management needs against the 85°C maximum junction temperature rating.
Part Context
This part belongs to the SG3525A series of pulse width modulator integrated circuits. The series is engineered to provide improved performance and reduced external component counts compared to earlier generations. It serves as a core control element in various regulated DC-DC conversion architectures.
Replacement Considerations
Compatible alternatives include the SG2525AN (PDIP-16) and SG2525AP (SOIC-16 tube). Verify pin compatibility and package dimensions before substitution.
