Overview
The LM5156HPWPR is a non-synchronous switching controller manufactured by Texas Instruments, designed for high-voltage applications. It supports Boost, Flyback, and SEPIC topologies with a wide input voltage range of 3.5 V to 60 V. The device features an adjustable switching frequency from 100 kHz to 2.2 MHz and delivers up to 1.5 A output current. It operates within a temperature range of -40°C to +125°C and is housed in a 14-pin HTSSOP package.
Feature Summary
- Supports multiple converter topologies including Boost, Flyback, and SEPIC configurations
- Features a wide input voltage range suitable for diverse power supply requirements
- Includes integrated protection mechanisms such as over-current protection and thermal shutdown
Applications
- Industrial power supplies
- Automotive electronics systems
- Telecommunications infrastructure equipment
Procurement Notes
Verify the specific suffix 'PWPR' corresponds to the HTSSOP-14 package and tape-and-reel quantity of 2000 units. Confirm that the component meets AEC-Q100 automotive qualification standards if required for your application. Ensure compatibility with your PCB footprint and reflow soldering profile specifications before finalizing procurement orders.
Selection Notes
Select this controller when designing circuits requiring high input voltages up to 60 V without synchronous rectification. Consider the 2.2 MHz maximum frequency for smaller passive component sizes. Evaluate the 490 uA quiescent current against system standby power constraints. Verify that the 1.5 A current limit aligns with the intended load requirements and thermal management capabilities of the design.
Part Context
This component belongs to the LM5156x family of wide VIN switching controllers from Texas Instruments. It is part of the broader portfolio of power management ICs aimed at industrial and automotive markets. The device complements other solutions like the LM5176 series, offering distinct topology support and voltage ranges for flexible system architecture designs.
Replacement Considerations
The LM51561HPWPR serves as a direct functional substitute within the same family, sharing identical electrical characteristics and pinout configuration. Both components utilize the HTSSOP-14 package and support the same Boost, Flyback, and SEPIC topologies with equivalent performance metrics.
