TDK FS160x µPOL™ DC-DC Converters

TDK FS160x µPOL™ DC-DC Converters feature full elementary and increased performance in a compact, power-dense package with 3.3mm x 3.3mm x 1.35mm dimensions. These converters are easy to integrate and offer a wide input voltage range of 4.2V to 16V and three continuous load capacities: 3A, 4A, and 6A. The featured on-chip pulse-width modulation (PWM) controller and integrated MOSFETs, with an incorporated inductor and capacitors, result in an extremely compact and accurate regulator. Built-in protections include pre-biased start-up, overvoltage protection, soft-start protection, thermal shutdown with auto-recovery, and thermally compensated overcurrent protection with hiccup mode. The low-profile package is suitable for automated assembly using standard surface-mount equipment. TDK FS160x µPOL DC-DC Converters are ideal for big data, artificial intelligence (AI), 5G cells, and the Internet of Things (IoT).
