SP1237F
It is a synchronous step-down regulator with an output current of up to 3.4A.
- Product Description
-
- Commodity name: SP1237F
- 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 SP1237F is a synchronous step-down regulator with a 2.4A 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 SP1237F operates in CV (constant voltage) mode, and the OCP current value is set by a current sensing power resistor.
The SP1237F is suitable for DC/DC switching power supply applications when a current limiting function is required. These devices come in an SOP-8L package and require very few external components for operation.Features
