Buck Regulator Achieves High Efficiency
Exhibiting an input voltage range from 3 V to 24 V, Fairchild Semiconductor’s FAN2108 8-A TinyBuck DC/DC buck regulator delivers 92% efficiency at 3.3-V output and 87% efficiency at 1.8-V output with 12-V input and 8-A load current, and peak efficiency of 95% at 5-V input and 3.3-V output. The 5-mm × 6-mm MLP-packaged component integrates a controller, MOSFETs, a boot diode, and pre-bias startup. The RoHS-compliant device protects from overvoltage, over-current, short-circuit and over-temperature. The regulator utilizes Pb-free terminals, and has been characterized for moisture sensitivity in accordance to IPC/JEDEC standard J-STD-020. Pricing is $1.41 each in 1,000 quantities.
