NAME
FUNCTION
Dual Mode?, Low-Battery Input. Connect to IN to set the low-battery threshold to 3.6V (no resistors
1
LBI
needed). Connect LBI to a resistor-divider for an adjustable LBI threshold. When V IN is below the set
threshold, LBO output switches low. LBO is deactivated and forced low when V IN is below the dead-battery
(DBI) threshold and when all REGs are disabled.

CC1

BKBT
REG1 Compensation Node. Connect a series resistor and capacitor from CC1 to GND to compensate the
regulation loop. See the Compensation and Stability section .
REG1 Feedback Input. Connect FB1 to GND to set V1 to 3.3V. Connect FB1 to external feedback resistors
for other output voltages.
Input Connection for Backup Battery. This input can also accept the output of an external boost converter.
Also known as VCC_BATT. V7 is always active if main or backup power is present. It is the first regulator

that powers up. V7 has two states:
1) V7 tracks V1 if ON1 is high and V1 is in regulation.
2) V7 tracks V BKBT when ON1 is low or V1 is out of regulation.

V1
REG1 Voltage-Sense Input. Connect directly to the REG1 output voltage. The output voltage is set by FB1
to either 3.3V or adjustable with resistors.

SLPIN Input to V1 and V2 Sleep Regulators. The input to the standby regulators at V1 and V2. Connect SLPIN to IN.

V2
REG2 Voltage-Sense Input. Connect directly to the REG2 output voltage. The output voltage is set by FB2
to either 1.8V/2.5V (MAX1586A, MAX1587A), 3.3V/2.5V (MAX1586B), or adjustable with resistors.
REG2 Feedback Input. Connect to GND to set V2 to 2.5V on all devices. Connect FB2 to IN to set V2 to

1.8V on the MAX1586A and MAX1587A. Connect FB2 to IN to set V2 to 3.3V on the MAX1586B. Connect
FB2 to external feedback resistors for other voltages.

CC2
REG2 Compensation Node. Connect a series resistor and capacitor from CC2 to GND to compensate the
regulation loop. See the Compensation and Stability section.
Power-OK Output. Open-drain output that is low when any of the V1–V6 outputs are below their regulation
threshold. When all activated outputs are in regulation, POK is high impedance. POK maintains a valid low

POK
output with V7 as low as 1V. POK does not flag an out-of-regulation condition while REG3 is transitioning
between voltages set by serial programming. POK also does not flag for any REG channel that has been
turned off; however, if all REG channels are off (V1–V6), then POK is forced low. If V IN < V UVLO , then POK is
low. POK is expected to connect to nVCC_FAULT.

SCL
Serial Clock Input
Serial Data Input. Data is read on the rising edge of SCL. Serial data programs the REG3 (core) and REG6

SDA
(VCC_USIM) voltage. REG3 and REG6 can be programmed even when off, but at least one of the ON_ pins
must be logic-high to activate the serial interface. On power-up, REG3 defaults to 1.3V and REG6 defaults
to 0V.

PWM3
LBO
Force V3 to PWM at All Loads. Connect PWM3 to GND for normal operation (skip mode at light loads). Drive
or connect high for forced-PWM operation at all loads for V3 only.
Low-Battery Output. Open-drain output that goes low when V IN is below the threshold set by LBI.
