- Product Description
-
- Commodity name: SP1238F
- 封装: SOP8
- 品牌: Wuxi Silicon Power Microelectronics
It is a synchronous step-down regulator with an output current of up to 3.4A.
The SP1238F is a synchronous step-down regulator with a 3.1A output current. It is designed to operate over a wide input voltage range of 8V to 30V. Internal compensation requires a minimal number of readily available standard external components.
The SP1238F operates in CV (constant voltage) mode, and the OCP current value is set by the current sensing power resistor.
The SP1238F is suitable for DC/DC switching power supply applications requiring current limiting functionality. These devices come in an SOP-8L package and require very few external components for operation.Features
