2.5A恒定输出电流固定52KHz频率3.6V至32V输入电压CXSD62248效率高达95%PWM控制电路能将占空比从0线性调整到100%

The CXSD62248 is a 52 KHz fixed frequency monolithic step down switch mode regulator with a built in internal Power MOSFET. It achieves 2.5A continuous output current over a wide input supply range with excellent load and line regulation. The device includes a voltage reference, oscillation circuit, error amplifier, internal PMOS and etc. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An enable function, an over current protection function and a short circuit protection function are built inside. An internal compensation block is built in to minimize external component count. The CXSD62248 serves as ideal power supply units for portable devices.
