REG N Base Drive. Open drain of an internal P-channel MOSFET. Connect to the base of an
external NPN linear-regulator pass transistor.
Logic Linear-Regulator (REG L) Base Drive. Open drain of an internal N-channel MOSFET. Connect
to the base of an external PNP linear-regulator pass transistor.
REG L Feedback Input. FBL regulates to 1.25V (typ). Connect to the center tap of a resistive
voltage-divider between the REG L output and the analog ground plane to set the output voltage.
Place the resistive voltage-divider close to this pin.
Gamma Linear-Regulator (REG G) Base Drive for the MAX1513. Open drain of an internal N-channel
MOSFET. Connect to the base of an external PNP linear-regulator pass transistor. Not internally
connected for the MAX1514.
REG G Feedback Input for MAX1513. FBG regulates to 1.25V (typ). Connect to the center tap of a
resistive voltage-divider between the REG G output and the analog ground plane to set the output
voltage. Place the divider close to the FBG pin. Not internally connected for the MAX1514.
Gate-On Linear-Regulator (REG P) Feedback Input. FBP regulates to 1.25V (typ). Connect to the
center tap of a resistive voltage-divider between the REG P output and the analog ground plane to
set the output voltage. Place the resistive-divider close to this pin.
REG P Base Drive. Open drain of an internal N-channel MOSFET. Connect to the base of an
external PNP linear-regulator pass transistor.
Ground
External MOSFET Gate Drive. Drives the gate of the step-up switching regulator’s MOSFET.
Supply Input. IN powers all the internal circuitry of the MAX1513/MAX1514. The input voltage range
is from 2.7V to 5.5V. Bypass with a 0.1µF ceramic capacitor between IN and GND. Place the
capacitor within 5mm of IN.
Current-Sense-Comparator Noninverting Input. Connect CS+ and CS- to the lossless current-sense
network. See the Lossless Current Sense section.
Current-Sense-Comparator Inverting Input. Connect CS+ and CS- to the lossless current-sense
network. See the Lossless Current Sense section.
Main Step-Up Regulator Feedback Input. FB regulates to 1.25V (typ). Connect to the center tap of a
resistive voltage-divider between the main output (V
main step-up regulator output voltage. Place the resistive-divider close to this pin.
