Product Description
DiodesZetex AP3781S-13 is a high-performance power supply controller IC designed for AC/DC power supply management in battery charger and adapter circuits. This device offers precise regulation of output voltage and current on the primary side through pulse frequency modulation in discontinuous conduction mode.
The controller comes in an 8-pin SO-8 surface mount package, with a compact length of 4.9mm and height of 1.45mm, enabling space-saving PCB layouts suitable for manufacturing and industrial electronic designs. It operates with a switching frequency of 20kHz, ensuring efficient power conversion and minimal noise generation.
Engineered to operate over a wide temperature range of -40°C to 150°C, the AP3781S-13 is suitable for challenging industrial and commercial environments. Its voltage input range spans from -0.3V to a maximum of 8V, facilitating versatile power management applications.
This controller implements primary side regulation eliminating the need for an opto-coupler, which enhances reliability and reduces component count. Additionally, it supports external adjustable over-temperature protection, safeguarding device and system integrity during fault conditions.
Typical use cases include industrial power supply systems, battery chargers, and electronic adapters for consumer and commercial products. The device’s compact form factor and surface mount compatibility make it ideal for modern electronics manufacturing and design.
