Product Summary

The SC1151CS voltage mode controller contains most of the circuitry necessary to implement a DC/DC converter for powering advanced microprocessors such as Klamath, both in single and multiple processor configurations. The SC1151CS features an integrated 5 bit D/A converter, pulse by pulse current limiting, integrated power good signaling, logic compatible shutdown and on-board over voltage protection (OVP). The SC1151CS operates at a fixed frequency of 200kHz, providing an optimum compromise between size, efficiency and cost in the intended application areas.

Parametrics

SC1151CS absolute maximum ratings: (1)VCC to GND, VIN: -0.3 to 7 V; (2)PGND to GND: ± 1 V; (3)BST to GND: -0.3 to 15 V; (4)Operating Temperature Range, TA: 0 to 70 ℃; (5)Storage Temperature Range, TSTG: -65 to +150 ℃; (6)Lead Temperature (Soldering): 10 sec; (7)TLEAD: 300 ℃.

Features

SC1151CS features: (1)85% efficiency; (2)5 bit DAC for output programmability; (3)On chip power good and OVP functions; (4)Designed for Intel Klamath VRM8.1 requirements.
