PMICs for Multimedia Application Processors
in a 3.0mm x 2.5mm WLP MAX8893A/MAX8893B/MAX8893C
General Description
The MAX8893A/MAX8893B/MAX8893C power-manage-
ment integrated circuits (PMICs) are designed for a
variety of portable devices including cellular handsets.
The PMICs include a high-efficiency step-down DC-DC
converter, five low-dropout linear regulators (LDOs) with
programmable output voltages, individual power-on/
off control inputs, a load switch, and a USB high-speed
switch. These devices maintain high efficiency with a low
no-load supply current, and the small 3.0mm x 2.5mm
WLP package makes them ideal for portable devices.
The step-down DC-DC converter utilizes a proprietary
4MHz hysteretic PWM control scheme that allows for
ultra-small external components. Internal synchronous
rectification improves efficiency and eliminates the exter-
nal Schottky diode that is required in conventional step-
down converters. Its output voltage is programmable by
the I2C serial interface and output current is guaranteed
up to 500mA.
LDO1, LDO4, and LDO5 offer low 45FVRMS output noise
and low dropout of only 100mV at 100mA. They deliver
up to 300mA, 150mA, and 200mA continuous output cur-
rents, respectively. LDO2 and LDO3 each deliver 300mA
continuous output current with very low ground current.
All LDO output voltages are programmable by the I2C
serial interface. Three standard versions of the PMIC are
available with different LDO default startup voltages (see
Table 1).
The MAX8893A/MAX8893B/MAX8893C are available in
a 3.0mm x 2.5mm, 30-bump WLP package.
