LM51770EVM-HV
LM51770 buck-boost controller evaluation module
LM51770EVM-HV
概述
The LM51770EVM-HV evaluation module (EVM) demonstrates a flexible high-power buck-boost design using the LM51770. The EVM is configured to operate from an input voltage range of 36V to 48V and produce a regulated 48V output with up to 4A load current. The EVM operates with a switching frequency of 380kHz. Most settings of the device are adjusted or set through jumpers, such as operation mode (PSM or fPWM), bias supply and external clock synchronization.
特性
- Wide input voltage range
- Ultra high (> 95%) peak power conversion efficiency
- Adjustable output voltage using feedback resistor divider
- Optional synchronization (SYNC)
- Easy configuration of current monitor or limiter
- Programmable input undervoltage lockout (UVLO) threshold and hysteresis
- Output constant voltage (CV) and constant current (CC) options
- Setting of configuration resistor RCFG through DIP switches
