LM2832YMY

LM2832YMY Description

The LM2832YMY from Texas Instruments is a high-efficiency, 2A step-down (Buck) DC-DC switching regulator with an adjustable output voltage range of 0.6V to 4.5V. Designed for surface-mount applications, it operates over a 3V to 5.5V input range, making it ideal for low-voltage power conversion in space-constrained designs. With a switching frequency of 550kHz, it balances efficiency and component size, reducing the need for large external inductors. The device is packaged in an 8-pin HVSSOP and supplied in Tape & Reel (TR) for automated assembly. Though marked as obsolete, it remains a reliable choice for legacy systems requiring stable, high-current power regulation.
