OB25133JPA SOP-7 AC-DC Controllers and Regulators SMD
The OB25133JPA SOP-7 AC-DC Controllers and Regulators SMD, manufactured by On-Bright Electronics, is a high-performance integrated circuit designed for efficient power management in low-power applications. Housed in a compact SOP-7 surface-mount package, this controller is tailored for space-constrained designs, making it an excellent choice for modern electronics such as battery chargers, adapters, and small appliance power supplies. Its advanced primary-side sensing technology eliminates the need for opto-couplers and external voltage references like the TL431, simplifying circuit design, reducing component count, and lowering overall production costs.
Features:
- High-precision constant current (CC) and constant voltage (CV) regulation.
- Primary-side sensing technology, eliminating the need for opto-couplers and TL431.
- Integrated PWM controller for efficient power conversion.
- Over-voltage protection (OVP), over-current protection (OCP), and thermal shutdown.
- Compact SOP-7 package for space-saving designs.
- Wide input voltage range, typically 85VAC to 265VAC.
- High efficiency, minimizing heat generation and energy loss.
- RoHS-compliant for environmentally friendly manufacturing.
