µPMICs for Multimedia Application Processors

in a 3.0mm x 2.5mm WLP

General Description

Features

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.

High-Efficiency Step-Down Converter

Guaranteed 500mA Output Current

Up to 4MHz Switching Frequency

Programmable Output Voltage from 0.8V to 2.4V

Dynamic Voltage Scaling with Programmable

Ramp Rate

Three Low-Noise LDOs with Programmable

Output Voltages

Two Low Supply Current LDOs with

Programmable Output Voltages

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.

Low On-Resistance Load Switch

USB High-Speed Switch with 15ꢀV ESD

Individual Enable Control for All Regulators and

Switches

I²C Serial Interface

LDO1, LDO4, and LDO5 offer low 45FV

output noise

RMS

Overcurrent and Thermal Protection for All LDOs

3.0mm x 2.5mm x 0.64mm, 30-Bump WLP

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).
