Maxim Integrated Products introduces the MAX17065 highly integrated power-management IC (PMIC) that includes a step-up DC-DC converter, an inverting DC-DC converter, regulated positive and negative charge pumps, and a low-dropout linear regulator (LDO). Developed using Maxim's proprietary high-voltage technology, this PMIC integrates all power functions required for active-matrix, organic light-emitting diode (AM-OLED) displays. The MAX17065 thus provides a cost-effective, high-performance solution for cell phones, digital still cameras (DSCs), MP3 players, and other consumer products.
The MAX17065 ensures optimal performance while maximizing flexibility. Operating from a +2.3V to +4.5V input supply, the step-up converter provides a fixed +5.35V output with up to 94% efficiency. The inverting converter features an adjustable, -0.5V to -5V output and is up to 83% efficient. Each switching converter has a cycle-by-cycle current limit, selectable SKIP and forced-PWM modes, and a selectable switching frequency of 600kHz/1.2MHz that allows for the use of small external inductors. The output voltage of the positive charge pump can be programmed between +5.5V and +9V, while the negative charge pump can be programmed between -0.5V and -5V. The LDO provides a +1.9V output for loads up to 60mA.
To save board space, the MAX17065 eliminates external power components by integrating synchronous rectifiers. Additionally, an I2C-compatible interface programs the switching frequency, operating mode, and current limit of the step-up and inverting converters, as well as the output voltages of the inverting converter and charge pumps.
The MAX17065 is available in a space-efficient, 4mm x 4mm, 28-pin TQFN package, and is fully specified over the -40 degrees Celsius to +85 degrees Celsius extended temperature range. Pricing starts at $1.20 (1000-up, FOB USA).
