The MAX17014ETM+T is a synchronous, dual output Switched Mode Power Supply (SMPS) optimized for single Li+ ion cell systems. This power management IC (PMIC) is specially designed for handheld devices with applications including personal digital assistant (PDA), portable digital audio/video players, digital still cameras, and global positioning systems (GPS). It is a highly integrated PMIC that contains two independent DC-DC converters with output tracking to maintain an optimal output voltage. It also features a low dropout regulator (LDO) that is capable of outputting up to 250mA, and uses automatic power saving features to increase battery life.

The MAX17014ETM+T provides two buck DC-DC converters labeled BUCK1 and BUCK2. The BUCK1 converter is optimized for input voltage range between 2.5V to 5.5V, and can have its output range from 0.7V-5.5V with 0.1V resolution. The BUCK2 converter is optimized for input voltage range from 0.7V to 5.5V and has an output voltage range from 0.5V-3.3V with 0.05V resolution. Both converters also have integrated power switches for inrush current protection, and operate in one of three modes: Pulse-Width Modulation (PWM) mode, Pulse-Frequency Modulation (PFM) mode, or Burst Mode operation (BM). The MAX17014ETM+T also provides an integrated LDO voltage regulator with an input voltage range from 2.5V to 5.5V and an output voltage range from 0.9V to 3.3V with 0.2V resolution. The LDO can provide up to 250mA and also has an integrated power switch.

The MAX17014ETM+T is a highly integrated power supply solution for single Li+ cell applications. It combines two buck converters and an LDO in a single package to reduce external component requirements and minimize board space. The output tracking of the two buck converters save power because the buck converter can automatically adjust the output voltage to maintain an optimal voltage for the load, allowing for higher efficiency operation. The integrated LDO is capable of providing 250mA for more power intensive operations. The MAX17014ETM+T also includes dynamic power management (DPM) which enables the device to switch between PWM mode, PFM mode, and BM operation depending on the load conditions, resulting in further power savings.

The MAX17014ETM+T is an efficient, power-saving dual-output PMIC designed for single Li+ cell systems. It is designed to reduce board size, simplify design, and maximize battery life. The integrated buck converters, LDO, and DPM help optimize performance and maximize efficiency. The MAX17014ETM+T is an ideal solution for a wide range of handheld devices such as personal digital assistants (PDAs), portable digital audio/video players, digital still cameras, and global positioning systems (GPS).
