Ricoh RN5RK Series VFM Step-Up DC/DC Converter Datasheet
The RN5RKxx1A/xx1B/xx2A Series are CMOS-based VFM (Chopper) Step-up DC/DC converter ICs designed for ultra-low supply current and high output voltage accuracy. The RN5RKxx1A/xx1B models include an internal driver transistor with low ON resistance, while the RN5RKxx2A model utilizes an external transistor drive pin to support larger output currents. These ICs are packaged in SOT-23-5 for high-density mounting.
