Overview
SE3837B is a synchronous step-down DC-DC converter with an input voltage withstand rating up to 40V, normal operation across a 4.5–40V input voltage range, and the capability to achieve precise constant-current and constant-voltage control. The SE3837B requires no external compensation, relying on its built-in stable loop to realize CC/CV control. The output voltage is adjustable, and the output current can be set via an external resistor. The SE3837B is a fully featured, extremely easy-to-use CC/CV step-down DC-DC converter that combines application flexibility and versatility with high performance and an outstanding price-to-performance ratio.
