FS3303 µPOL™ Buck Regulator

TDK FS3303 µPOL™ Buck Regulator is an easy-to-use, fully integrated, and highly efficient micro-Point-of-Load (µPOL™) voltage regulator. This buck regulator, featuring an on-chip Pulse-Width Modulation (PWM) controller and integrated MOSFETs, incorporates an inductor, resulting in an ultra-compact 3A synchronous buck regulator. The FS3303 regulator operates at a 2.75V to 5.5V input voltage range and -40°C to 125°C operating temperature range. This regulator built-in protection features include soft-start protection, over-voltage protection, thermally compensated overcurrent protection with hiccup mode, and thermal shutdown with auto-recovery. The FS3303 regulator is ideal for optical networking systems, FPGAs, ASICs, SoCs, storage requirements, industrial applications, LDO replacement at high efficiency, drones, robotics, IoT, and portable devices.
