µPMIC for Microprocessors or DSPs in Portable Equipment
General Description
The MAX8620Y micro-power-management integrated
circuit (µPMIC) powers low-voltage microprocessors or
DSPs in portable devices. The µPMIC includes a high-
efficiency step-down DC-DC converter, two low-
dropout linear regulators (LDOs), a microprocessor
reset output, and power-on/off control logic. This device
maintains high efficiency at light loads with a low 115µA
supply current, and its miniature TDFN package makes
it ideal for portable devices.
The MAX8620Y’s step-down DC-DC converter utilizes a
proprietary 4MHz hysteretic-PWM control scheme that
allows for ultra-small external components. Internal syn-
chronous rectification improves efficiency and elimi-
nates the external Schottky diode that is required in
conventional step-down converters. The output voltage
is adjustable from 0.6V to 3.3V, with guaranteed output
current up to 500mA.
The MAX8620Y’s two LDOs offer low 45µVRMSoutput
noise and a low dropout of only 200mV at 200mA. Each
LDO delivers at least 300mA of continuous output cur-
rent. The output voltages are pin selectable from 1.8V
to 3.3V for flexibility.
A microprocessor reset output (RESET) monitors OUT1
and warns the system of impending power loss allow-
ing safe shutdown. RESETasserts during power-up,
power-down, shutdown, and fault conditions where
VOUT1is below its regulation voltage.

MAX8620Y
µPMIC for Microprocessors or DSPs
in Portable Equipment
Detailed Description
The MAX8620Y µPMIC is designed to power low-core-
voltage microprocessors or DSPs in portable devices.
The µPMIC contains a fixed-frequency, high-efficiency
step-down converter; two low-dropout regulators
(LDOs); a 30ms (min) reset timer; and power-on/off
control logic (Figure1).
Step-Down DC-DC Control Scheme
The MAX8620Y step-down converter is optimized for
high-efficiency voltage conversion over a wide load
range while maintaining excellent transient response,
minimizing external component size, and minimizing
output voltage ripple. The DC-DC converter (OUT3)
also features an optimized on-resistance internal
MOSFET switch and synchronous rectifier to maximize
efficiency. The MAX8620Y utilizes a proprietary hys-
teretic-PWM control scheme that switches with nearly
fixed frequency up to 4MHz, allowing for ultra-small
external components. The step-down converter output
current is guaranteed up to 500mA.
When the step-down converter output voltage falls
below the regulation threshold, the error comparator
begins a switching cycle by turning the high-side pFET
switch on. This switch remains on until the minimum on-
time (tON) expires and the output voltage is in regula-
tion or the current-limit threshold (ILIM3P) is exceeded.
Once off, the high-side switch remains off until the mini-
mum off-time (tOFF) expires and the output voltage
again falls below the regulation threshold. During this
off period, the low-side synchronous rectifier turns on
and remains on until either the high-side switch turns
on or the inductor current reduces to the rectifier-off
current threshold (ILXOFF= 30mA (typ)). The internal
synchronous rectifier eliminates the need for an exter-
nal Schottky diode.

MAX8620Y
Voltage-Positioning Load Regulation
As seen in Figure2, the MAX8620Y uses a unique step-
down converter feedback network. By taking feedback
from the LX node through R1, the usual phase lag due
to the output capacitor is removed, making the loop
exceedingly stable and allowing the use of a very small
ceramic output capacitor. This configuration causes the
output voltage to shift by the inductor series resistance
multiplied by the load current. This output-voltage shift
is known as voltage-positioning load regulation.
Voltage-positioning load regulation greatly reduces
overshoot during load transients, which effectively
halves the peak-to-peak output-voltage excursions
compared to traditional step-down converters. See the
Load-Transient Response graph in the Typical
Operating Characteristicssection.
Two low-dropout, low-quiescent-current, high-accuracy
linear regulators supply loads up to 300mA each. The
LDO output voltages are set using SEL1 and SEL2 (see
Table1). As shown in Figure3, the LDOs include an
internal reference, error amplifiers, p-channel pass tran-
sistors, internal-programmable voltage-dividers, and an
OUT1 power-good comparator. Each error amplifier
compares the reference voltage to a feedback voltage
and amplifies the difference. If the feedback voltage is
lower than the reference voltage, the pass-transistor
gate is pulled lower, allowing more current to pass to
the outputs and increasing the output voltage. If the
feedback voltage is too high, the pass-transistor gate is
pulled up, allowing less current to pass to the output.
