ELM610DA _{1.3A 36V PWM step down DC/DC converter}

■General description

ELM610DA consists of step-down switching regulator with PWM control, reference voltage source, oscillation

circuit, error amplifier, internal PMOS, etc. ELM610DA 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%.

ELM610DA 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, ELM610DA is able to function as step-down

switching regulator. By the small package of SOP-8, ELM610DA is capable of working as ideal power supply

units for portable devices while providing outstanding features such as low current consumption. Since this

converter accommodates input voltage up to 36V, ELM610DA is also suitable for operations which adopt AC

adapter.
