6 / 17 page 6 © 2008 Semtech Corp. www.semtech.com SC196A PRELIMINARY POWER MANAGEMENT Pin Descriptions Pin # Pin Name Pin Function 1 VIN Input power supply voltage 2 MODE MODE select pin - MODE = V IN to select 100% duty cycle function; MODE = GND to disable 100% duty cycle capability. 3 SYNC/PWM Oscillator synchronization input - Tie to V IN for forced PWM mode or GND to allow the part to enter PSAVE mode at light loads. Apply an external clock signal for frequency synchronization. 4EN Enable digital input - a high input enables the SC196A; a low disables and reduces quiescent current to less than 1μA. In shutdown, LX becomes high impedance. 5 VOUT Regulated output voltage and feedback for SC196A 6 VID0 Logic level bit 0 used in conjunction with VID1 to set the output voltage. Connect high or low as required to select the desired output voltage. If not connected, the output voltage will be indeterminate. 7 VID1 Logic level bit 1 used in conjunction with VID0 to set the output voltage. Connect high or low as required to select the desired output voltage. If not connected, the output voltage will be indeterminate. 8 GND Ground 9 PGND Power Ground 10 LX Inductor connection to the switching FETs |
