ELM612DA 3A 36V PWM step down DC/DC converter
■General 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 150kHz to 30kHz when overmuch current or short circuit occurs. Meanwhile, internal
compensation block is able to minimize the quantity of required external component. With internal P-channel
Power MOS, and externally connected coil, capacitor, and diode, ELM612DA is able to function as step-
down switching regulator. By the small package of SOP-8, ELM612DA is capable of working as ideal power
supply units for many devices while providing outstanding features such as low current consumption. Since this
converter accommodates input voltage up to 36V, ELM612DA is also suitable for AC adapter applications.
