MAX14720/MAX14750 Power-Management Solution General Description The MAX14720/MAX14750 are compact power-management solutions for space-constrained, battery-powered applications where size and efficiency are critical. Both devices integrate a power switch, a linear regulator, a buck regulator, and a buck-boost regulator. The MAX14720 is designed to be the primary powermanagement device and is ideal for either non-rechargeable battery (coin-cell, dual alkaline) applications or for rechargeable solutions where the battery is removable and charged separately. The device includes a button monitor and sequencer. The MAX14750 works well as a companion to a charger or PMIC in rechargeable applications. It provides direct pin control of each function and allows greater flexibility for controlling sequencing. The devices include two programmable micro-IQ, highefficiency switching converters: a buck-boost regulator and a synchronous buck regulator. These regulators feature a burst mode for increased efficiency during lightload operation. The low-dropout linear regulator has a programmable output. It can also operate as a power switch that can disconnect the quiescent load of system peripherals. The devices also include a power switch with batterymonitoring capability. The switch can isolate the battery from all system loads to maximize battery life when not operating. It is also used to isolate the battery-impedance measuremen...
