7 / 7 page  © 1997 SEMTECH CORP. 652 MITCHELL ROAD NEWBURY PARK CA 91320 LOW VOLTAGE STEP-UP DC-DC CONVERTER SC1633 January 29, 1998 DEVICE OUTLINE - SO-8 PIN DESCRIPTIONS PIN 1: I LIM/SD (1) Connected to V IN pin through a resistor to set the switch peak current. It serves to protect the IC and induc- tor, as well as to improve efficiency and output ripple. However, the supply capability of the SC1633 is limited by the current limit resistor (see typical performance characteristics). The I LIM/SD pin should be shorted to VIN if limiting switch peak current is not required. (2) The SC1633 goes into shutdown mode and consumes less than 10µA when the I LIM/SD pin is pulled to ground. PIN 2: V IN Input supply. PIN 3: SW Drain of the power switch, to be con- nected to the inductor and diode. PIN 4: SGND Ground connected to the source of the power switch. PIN 5: CGND Ground for control circuits of the IC. It should be separated from SGND to avoid interference. PIN 6: LBO Open drain output of the battery low detector, with 45 Ohm “On Resis- tance” at V IN=2V. It is pulled low when the voltage on the LBI pin is below 1.22 volts. PIN 7: LBI The inverting input of the battery low detector, of which the non-inverting input is internally connected to the 1.22V voltage reference. PIN 8: V OUT The output voltage feeds back to the IC through this pin. PIN CONFIGURATION |
