Mouser Electronics, the industry’s leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the FS1525 25A stackable µPOL regulator from TDK. The FS1525 is an easy-to-use, fully integrated, and highly efficient micro-point-of-load (µPOL) voltage regulator. The regulator is engineered to meet the demands of AI servers, data center systems, edge computing, telecom and networking, industrial applications, and distributed point-of-load (PoL) power architectures.
The TDK FS1525 µPOL regulator, now available at Mouser, delivers 25A per module and up to 200A when stacking multiple units in vertical power-delivery designs. The ultra-compact, accurate regulator features an on-chip pulse-width modulation (PWM) controller, integrated MOSFETs, along with an incorporated inductor and capacitors. The FS1525 offers built-in protection, including pre-biased start-up, soft-start protection, thermally compensated overcurrent protection with hiccup mode, overvoltage protection, and thermal shutdown with auto-recovery. It also features ultra-fast transient response, ultra-low DC ripple, and true differential remote sensing for accurate voltage regulation at the point of load.
The TDK FS1525 provides programmable operation via I2C and PMBus protocols, enabling real-time telemetry, adaptive tuning, and fault management for voltage, current, and temperature monitoring. The compact, low-profile regulator measures 6.80mm x 7.65mm x 3.82mm and is suitable for automated assembly using standard-mount equipment. The FS1525 offers a plug-and-play design and requires no external components, simplifying designs, accelerating development, and reducing overall system costs.
The TDK EV1525-0800-25A/-50A/-100A µPOL evaluation boards help start development with the FS1525 regulator. The evaluation boards produce an output voltage (VOUT) of 0.8V for loads of 0A to 25A (EV1525-0800-25A), 0A to 50A (EV1525-0800-50A), or 0A to 100A (EV1525-0800-100A) from an input voltage (PVIN) of 12V.
