FUNCTION
LDO Enable Input. Drive ENA high to enable the LDO (OUTA). Drive low to disable the LDO.
Internal Regulator Output. Bypass V L to GND with a 4.7 F F capacitor.
Ground
DC-DC1 Converter Output. OUT1 supplies internal circuitry in standby mode reducing overall
current consumption. Connect a 0.1 F F capacitor from OUT1 to GND as close as possible to the IC.
If the DC-DC1 output is pulled below its power-on-reset threshold ( POR ), DC-DC2 and DC-DC3 are
automatically disabled.
DC-DC1 Converter Feedback Input. Connect FB1 to GND for a fixed 3.3V output. Connect to a
resistive divider to adjust the output voltage between 1.22V and 5.5V.
DC-DC2 Converter Output
DC-DC2 Converter Feedback Input. Connect FB2 to GND for a fixed 5V output. Connect to a
resistive divider to adjust the output voltage between 1.22V and 5V.
5V Linear Regulator Output. Connect an external capacitor of at least 4.7 F F from OUTA to GND.
External pMOS Output Drive Signal. ODRV turns off the pMOS during overvoltage events. If only
DC-DC1 is running, the overvoltage circuit is disabled and the external pMOS is turned off.
Bootstrap Capacitor Connection for DC-DC1. Connect a 0.47 F F capacitor from BST1 to LX1.
Battery Supply-Voltage Input. V INA supplies power to the V L regulator, the LDO, and DC-DC1.
DC-DC1 Converter Switching Node. Connect an LC filter to LX1. Use a capacitor with a maximum
ESR of 0.3 I . Unless there is an undervoltage lockout, DC-DC1 is always on when power is applied.
