Description
The MPM4720 is a fully integrated, high-efficiency, synchronous buck-boost power module with a built-in inductor. The device can operate from an input voltage (VIN) exceeding, equal to, or below the output voltage (VOUT).
The fixed 2MHz switching frequency (fSW) allows for the use of small external components, while internal compensation and soft start (SS) reduce the external component count. The MPM4720 employs current mode control with a fixed pulse-width modulation (PWM) frequency to improve stability and transient response.
For low-noise applications, a high-logic input on the MODE/SYNC pin allows the device to operate in fixed-frequency PWM mode under all load conditions.
The MPM4720 operates from a 1.2V to 5.5V VIN range and provides an adjustable VOUT that can be set between 1.5V and 5.5V.
The MPM4720 is available in a small ECLGA-14 (2.5mmx2.5mmx1.2mm) package.
