The MAX8958 provides two Quick-PWM VID controller supplies, three step-down converters, 13 low-dropout voltage regulators (LDOs), a real-time clock (RTC) with alarms, processor platform sideband signals, a clock output, backup battery charger, and a serial peripheral interface (SPI) for programming. It comes in a 5.4- by 5.7- by 0.4-mm wafer-level package.

The MAX17085B integrates a multi-chemistry battery charger, dual fixed-output Quick-PWM step-down controllers, and dual keep-alive linear regulators in a 5- by 5-mm thin quad flat no-lead (TQFN) package.
