Detailed Desc ription
The MAX886/MAX888 contain one high-efficiency, step-
down DC-DC converter, four low-dropout linear regula-
tors, and one regulated charge pump. The output
voltages of the switching regulator and the linear regula-
tors are software-programmable through the serial inter-
face. The regulated charge-pump output is factory set
at 5.25V. The devices also include reset and start-up
timers and a low-battery detect comparator (Figure 3).
500mA DC-DC Buc k Regulator 0
Regulator 0 is a low-noise, step-down, synchronous
DC-DC converter that can source a minimum of
500mA. High operating frequency (up to 925kHz) mini-
mizes output voltage ripple and reduces the size and
cost of external components. Guaranteed 100% duty-
cycle operation provides the lowest possible dropout
voltage, extending the useful life of the battery supply.
