Controller steps down voltages from 60 V

The LTC3812-5 synchronous step-down switching regulator controller directly steps down voltages from 60 V to output voltages ranging from 0.8 V to 93% of VIN . Features include a selectable frequency of 100 kHz to 1 MHz, selectable pulse skipping operation, 1-Ω gate drivers, current-mode control, and programmable soft-start.

Its 0.8-V reference has ±0.75% accuracy over the operating temperature range of –40° to +85°C. The device is housed in a 16-lead SSOP package, and also features a power-good signal, shutdown, undervoltage lockout, and output overvoltage. (From $3.25 ea/1,000—available now.)
