The OB5269CPA is a switching controller manufactured by On-Bright. It is an 8-pin surface mount device (SOP) that has a footprint of 150mil (3.81mm). The chip is RoHS compliant, meaning that it does not contain certain hazardous materials and thus supports environmental protection goals. It is intended to provide synchronous step-down and non-synchronous step-up control with internal power MOSFETs. It features low RDS(on) output control, current limit with foldback protection, frequency synchronization, current sensing, and spread spectrum modulation. It is suitable for a wide variety of applications and can support input voltage ranges from 4.5V to 60V.
