Introduction
LM5010SD is a high voltage, 1-Ampere synchronous buck regulator. It has a wide input voltage range of 4.5 V to 75 V and is designed to provide a regulated output voltage from 0.8 V to 60 V. The LM5010SD operates at a fixed frequency of 100 kHz, 200 kHz, or 400 kHz and utilizes a constant on-time, valley current-mode control scheme to provide fast transient response and excellent loop stability. The device features a high-side MOSFET and a low-side MOSFET with internal gate drivers, which allows for a simple and compact design. It also includes various protection features such as under-voltage lockout (UVLO), thermal shutdown, and over-current protection. The LM5010SD is available in a 10-lead, thermally enhanced WSON package, making it suitable for various applications such as telecom, industrial, and automotive power supplies.
