Maxim Introduces MicroPMIC for Multimedia Application Processors

Maxim Integrated Products introduced the MAX8893, a highly integrated microPMIC for multimedia application processors. This device includes one high-efficiency step-down converter, three low-noise LDOs, two low-supply-current LDOs, one low-on-resistance load switch, and one Hi-Speed USB switch-all in a 2.5mm x 3.0mm, 30-bump wafer-level package (WLP).

According to the company, this integration saves space and cost without sacrificing design flexibility. All regulators and switches have individual enable pins that allow designers to turn on/off different functional blocks to save power and extend battery life. Its high level of integration and functional block enable control make the MAX8893 a complete power-management solution for multimedia application processors in portable devices such as cellular handsets.

For enhanced performance, the integrated LDOs provide low 45µVRMS output noise and a low dropout of only 100mV at 100mA (LDOs 1,4 and 5), as well as a very low, 21µA ground current for longer battery life. These LDOs have programmable output voltages for ease of use in numerous applications. The 4MHz buck converter allows ultra-small external components and features dynamic voltage-scaling (DVS) control of the ramp rate (from 1mV/microsecond to 12mV/µs). The load switch features ultra-low on-resistance (50Ω, min) and operates from an input voltage of 0.8 to 2.4V.

Pricing for the MAX8993 starts at $1.95 (1000-up, FOB USA). A user-friendly evaluation kit is available to speed designs.
