2 / 6 page SC1150 © 1998 SEMTECH CORP. 652 MITCHELL ROAD NEWBURY PARK CA PROGRAMMABLE DC/DC CONTROLLER March 11, 1998 2 NOTES: (1) Low output currents, below the continuous conduction threshold will cause an increase in output voltage beyond the load regulation limit. For Application circuit 16935E see the regulation curve on sheet 5. (2) All VID codes not specifically listed here are invalid and cause shutdown exactly as if the shutdown pin had been asserted. xxxx refers to any valid VID code. ELECTRICAL CHARACTERISTICS Unless specified: V CC = 4.75V to 5.25V; GND = PGND = 0V; VOSENSE = VO; 0mV < (CSp-CSm) < 60mV; TA = 25 oC PARAMETER CONDITIONS VID 3210 MIN TYP MAX UNITS Output Voltage (2) I O = 2A in Application circuit 16935E 1111 1.980 2.000 2.020 V 1110 2.079 2.100 2.121 1101 2.178 2.200 2.222 1100 2.277 2.300 2.323 1011 2.376 2.400 2.424 1010 2.475 2.500 2.525 1001 2.574 2.600 2.626 1000 2.673 2.700 2.727 0111 2.772 2.800 2.828 0110 2.871 2.900 2.929 0101 2.970 3.000 3.030 0100 3.069 3.100 3.131 0011 3.168 3.200 3.232 0010 3.267 3.300 3.333 0001 3.366 3.400 3.434 0000 3.465 3.500 3.535 Load Regulation I O = 0.3A to 13A (1) xxxx 1 % Line Regulation xxxx 0.5 % UV Lockout xxxx 4.2 V Current Limit Voltage xxxx 60 70 80 mV Oscillator Frequency xxxx 180 200 220 kHz Oscillator Max Duty Cycle xxxx 90 95 % DH Sink/Source Current BST - DH = 4.5V, DH - PGND = 2V xxxx 1 A Output Voltage Tempco xxxx 65 ppm/ oC |
