LM251772EVM-PD
LM251772 evaluation module
LM251772EVM-PD
概述
The LM251772EVM-PD demonstrates a flexible high-power buck-boost design using the LM251772. The evaluation module (EVM) is configured to operate from an input voltage range of 9V to 36V and to produce a regulated 5V to 48V output with up to a 5A load current. The EVM operates with a switching frequency of 320kHz. Most of the device settings are easily adjusted or set through jumpers, like: operation mode (PSM or fPWM), bias supply, and external clock synchronization.
特性
- Input voltage range: 9V to 36V
- Output voltage 5V to 48V (5V default, adjustable 5V to 48V) with up to 5A (240W)
- High efficiency, synchronous buck-boost conversion
- Easy access to configuration features
- Flexible design using standard MOSFETs
