The LM2832 is a monolithic, high frequency, PWM step-down DC/DC converter in a 6 Pin LLP and a 8 Pin eMSOP package. It provides all the active functions to provide local DC/DC conversion with fast transient response and accurate regulation in the smallest possible PCB area.
The LM2832 regulator is a monolithic, high‑frequency PWM step‑down DC‑DC converter offered in 6‑Pin LLP and 8‑Pin eMSOP packages. It provides local DC‑DC conversion with fast transient response, accurate regulation, and a small PCB footprint, requiring only a few external components.
Typical applications include core power for HDDs, set‑top boxes, USB‑powered devices, and DSL modems. The device features internal soft‑start, pulse‑by‑pulse current limit, thermal shutdown, and over‑voltage protection, making it suitable for a wide range of consumer and industrial designs.
