ELM612DA
description
ELM612DA is a of step-down switching regulator with PWM control, reference voltage source, oscillation circuit, error amplifier, internal PMOS, etc. ELM612DA provides low-ripple power, high efficiency, and excellent transient characteristics; PWM control circuit is able to vary the duty ratio linearly from 0 up to 100%. ELM612DA also contains error amplifier circuit as well as soft-start circuit that prevents overshoot at during startup. Internal enable function, over current protect function and short circuit protect function will reduce the operation frequency from 150k Hz to 30k Hz when overmuch current or short circuit occurs. Meanwhile, internal pensation block is able to minimize the quantity of required external ponent. With internal P-channel Power MOS, and externally connected coil, capacitor, and diode, ELM612DA is able to function as stepdown switching regulator. By the small package of SOP-8, ELM612DA is capable of working as ideal power supply units for many...
