RICOH R1210N Series 8V Input PWM Step-up DC/DC Converter handbook

Update: 29 September, 2023

The R1210N Series are low supply current, CMOS-based PWM step-up DC/DC converters. By simply using an inductor, a diode, and a capacitor as external components, a high-efficiency step-up DC/DC converter can be easily configured. The xx1 version with an internal output transistor and the xx2 version with an external transistor are available. The oscillator frequency can be selected from 100kHz or 180kHz. The xx1A version is also available, which contains a basic frequency changeover circuit that switches the oscillator frequency from 100kHz to 35kHz when output load is reduced. R1210N also has a function that detects drastic changes in output voltage and reduces the amount of overshoot/undershoot by switching control mode.
