1 / 6 page  SC1151 © 1998 SEMTECH CORP. 652 MITCHELL ROAD NEWBURY PARK CA PROGRAMMABLE DC/DC CONTROLLER FOR ADVANCED MICROPROCESSORS March 11, 1998 1 ABSOLUTE MAXIMUM RATINGS Parameter Symbol Maximum Units V CC to GND V IN -0.3 to 7 V PGND to GND ± 1 V BST to GND -0.3 to 15 V Operating Temperature Range T A 0 to 70 °C Storage Temperature Range T STG -65 to +150 °C Lead Temperature (Soldering) 10 sec T LEAD 300 °C Pentium is a registered trademark of Intel Corporation TEL:805-498-2111 FAX:805-498-3804 WEB:http://www.semtech.com DESCRIPTION The SC1151 voltage mode controller contains most of the circuitry necessary to implement a DC/DC con- verter for powering advanced microprocessors such as Klamath, both in single and multiple processor con- figurations. The SC1151 features an integrated 5 bit D/A con- verter, pulse by pulse current limiting, integrated power good signaling, logic compatible shutdown and on-board over voltage protection (OVP). The SC1151 operates at a fixed frequency of 200kHz, providing an optimum compromise between size, effi- ciency and cost in the intended application areas. The integrated D/A converter provides programmabil- ity of output voltage from 2.0V to 3.5V in 100mV in- crements and 1.80V to 2.05V in 50mV increments with no external components. The SC1151 provides an OVP output which can be used to trigger a crowbar circuit for true over voltage protection. APPLICATIONS • Klamath microprocessor supplies • Klamath VRM modules • 1.8V to 3.5V microprocessor supplies • Programmable power supplies FEATURES • 85% efficiency • 5 bit DAC for output programmability • On chip power good and OVP functions • Designed for Intel Klamath VRM8.1 requirements ORDERING INFORMATION DEVICE (1) PACKAGE TEMP RANGE (T J) SC1151CS SO-16 0° to 125°C BLOCK DIAGRAM VCC VCC ERROR AMP D/A AND SHUTDOWN LOGIC DECODED SHUTDOWN SIGNAL OSCILLATOR LEVEL SHIFT AND DRIVE 1.25V REF + - + - CURRENT LIMIT + - + - CSm VID0 VID2 VID1 VID3 VOSENSE PWRGOOD BST DH VCC SHUTDOWN OVP GND PGND R S Q + - 70mV CSp + - VID4 A17043A PIN CONFIGURATION 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 PWRGOOD VID0 VID1 VID2 VID3 BST DH VOSENSE GND SHUTDOWN PGND VCC CSp CSm OVP VID4 Note: (1) Add suffix ‘TR’ for tape and reel. |
