5-Output Power-Management IC For Low-Cost PDAs
General Description
The MAX1559 is a complete power-management chip
for low-cost personal digital assistants (PDAs) and
portable devices operating from a 1-cell lithium-ion
(Li+) or 3-cell NiMH battery. It includes all the regula-
tors, outputs, and voltage monitors necessary for small
PDAs while requiring a bare minimum of external com-
ponents. Featured are four linear regulators, a DC-DC
boost converter for LCD bias, a microprocessor reset
output, and low-battery shutdown in a miniature QFN
package. For a compatible Li+ charger for both USB
and AC adapter inputs, refer to the MAX1551*.
The four linear regulators feature PMOS pass elements
for efficient low-dropout operation. A MAIN LDO sup-
plies 3.3V at 500mA. A signal-detect (SD) card-slot out-
put supplies 3.3V at 400mA. The COR1 LDO outputs 1V
at 250mA, and the COR2 LDO supplies 1.8V at 30mA.
The SD output and COR2 LDO have pin-controlled
shutdown. For other output-voltage combinations, con-
tact Maxim.
The DC-DC boost converter features an on-board MOSFET
and True Shutdown™ when off. This means that during
shutdown, input power is disconnected from the induc-
tor so that the boost output falls to 0V rather than
remaining one diode drop below the input voltage.
A µP reset output clears when the MAIN LDO achieves
regulation to ensure an orderly start. Thermal shutdown
protects the die from overheating.
The MAX1559 operates from a 3.1V to 5.5V supply and
consumes 50mA of no-load supply current. It is pack-
aged in a 1.3W, 16-pin thin QFN with a power pad on
the underside of the package. The MAX1559 is speci-
fied for operation from -40°C to +85°C.

ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
