Dual Synchronous DC/DC Controller Delivers Fast Powerup

Dual Synchronous DC/DC Controller Delivers Fast Powerup
Linear Technology Corp.

The LTC3887 dual output synchronous step-down dc/dc controller with I²C-based PMBus interface specifies a 70-ms power-up time and an ADC mode with an 8-ms update rate for one parameter. The device enables digital programming and read back for real-time control and monitoring of point-of-load converter functions. Programmable control parameters include output voltage, margining and current limits, input and output supervisory limits, power-up sequencing and tracking, switching frequency, and identification and traceability data. The LTC3887 regulates two independent outputs or can be configured for a two-phase single output. Up to six phases can be interleaved and paralleled An integrated amplifier provides true differential remote output voltage sensing. Available in a 40-pin, 6 mm x 6 mm QFN package, price starts at $5.47 each/1,000. For more information and a datasheet, visit http://www.linear.com/product/LTC3887
