APEK4447SLJ-01-T

• Product introduction

A4447It is a 2 A, high efficiency general-purpose buck regulator for a wide range of applications. Based on the resistor divider and a 0.8 V ±2% reference value, the output voltage is adjustable from 0.8 to 24 V. External components include an external clamping diode, inductor, and filter capacitor. The downtime depends on the external resistor. It can be operated in continuous and intermittent mode to maintain light load regulation. Due to the reverse recovery of the external clamp diode, the internal blanking circuit will be used for leakage transient flow. The typical blanking time is 200 ns.

The new device is ideal for a variety of end products, including applications requiring 2 A of output current with an input voltage range of 8 to 50 V, such as uninterruptible power supplies, point-of-sale (POS) applications, and industrial applications with 24 or 36 V buses.
