summary

NJM2393 is a step-down DC/DC converter IC that can operate at low voltage. The maximum duty cycle can be set to 100%, so even if the voltage difference between input and output is small, it is easy to maintain the stability of the output voltage. In addition, a 1.5A power transistor is built-in. The built-in pulse-by-pulse current limit circuit can be arbitrarily set with external resistors.
