OB2273MP SOT23 High Performance Current Mode PWM Controller

Product Description: OB2273MP SOT23 High Performance Current Mode PWM Controller

The OB2273MP is a high-performance current mode PWM (Pulse Width Modulation) controller housed in the compact SOT-23 package. Designed for use in power supply circuits, the OB2273MP offers efficient voltage regulation and precise control of switching power supplies. This controller is especially useful for DC-DC converters, AC-DC power supplies, and other voltage regulation applications, offering excellent stability and control in both continuous and discontinuous mode operation.

With built-in features like soft-start, under-voltage lockout (UVLO), and over-current protection, the OB2273MP provides robust performance in high-reliability applications. It is optimized for low-power designs, enabling efficient power conversion with minimal energy loss. The OB2273MP is ideal for applications requiring high-frequency switching and is commonly used in telecommunications, consumer electronics, and industrial power supplies.

Features:
