PWM Control 2A Step-Down Converter

PWM Control 2A Step-down Converter , LSP3133 consists of Step-down Switching Regulator with PWM control. These devices include a reference voltage source, oscillation circuit, error Amplifier and internal PMOS. LSP3133 provides low-ripple power, high efficiency, and excellent transient characteristics. The PWM control circuit is able to vary the duty ratio linearly from 0 up to 100%. This converter also contains an error Amplifier circuit as well as a soft-start circuit that prevents overshooting at startup. An enable function, an over current protect function and a short circuit protect function are built inside, and when OCP or SCP happens, the operation frequency will be reduced from 300KHz to 50KHz. Also, an internal compensation block is built in to minimum external component count. With the addition of an internal P-channel Power MOS, a coil, capacitors, and a Diode connected externally, these ICs CAN function as Step-down Switching Regulators They serve as ideal power supply units for portable devices when coupled with the SOP8L mini-package, providing such outstanding features as low current consumption. Since this converter CAN accommodate an input voltage up to 23V, it is also suitable for the operation via an AC adapter. By Lite-On Power Semiconductor
