Pin Function Description
5V output enable
. TTL-compatible input disables 5V linear regulator when set to logic
LOW. Serves as system global enable/disable when used with RC5023 companion
IC.
Oscillator timing capacitor
. Connecting an external capacitor to this pin sets the
internal oscillator frequency.
Ground
. Connect this pin to system ground so that ground loops are avoided.
12V output enable
. TTL-compatible input disables the switch-mode converter when
set to logic LOW.
Voltage feedback
. Input for the voltage feedback control loop.
FET Driver output for switch-mode converter
. Connect this pin to the gate of an
N-channel MOSFET. The trace from this pin to the MOSFET gate should be as
short as possible (<0.5").
5V linear regulator output
. Connect this pin to loads up to 40mA or to VCCL pin of
RC5023 when used in the notebook computer power supply system.
Battery Supply Voltage
. Connect to system battery or other 6V to 30V source.
