ELM610DA 1.3A 36V PWM step down DC/DC converter
■Application notes
PWM Control
ELM610DA is DC/DC converter which consists pulse-width modulation (PWM) system. In converters of
ELM610DA, the pulse width varies according toe the load current, within the range from 0 to 100%. The ripple
voltage produced by switching can easily be removed through the filter since switching frequency remains con-
stant; ELM610DA is capable of providing low-ripple power within broad ranges of input voltage and load cur-
rent.
