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.
