MPM4710GPA-P

MPM4710GPA-P 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) above, 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 MPM4710 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. Application includes optical modules, personal medical devices, time-of-flight (ToF) sensors or structured light systems.

• 1.8V minimum start-up input voltage (VIN)
• 1.2V to 5.5V operating VIN range, 1.5V to 5.5V output voltage (VOUT) range
• Typical 1A, Max 2A output current (IOUT)
• Fixed 2MHz or external synchronous switching frequency (fSW)
• Selectable pulse-skip mode (PSM) or pulse-width modulation (PWM) mode
• Typical 25μA quiescent current (IQ)
• Load disconnect during shutdown, internal soft start (SS) and compensation
• Power good (PG) indication, short-circuit protection (SCP) with hiccup mode
• Thermal shutdown
• ECLGA-14 package, operating temperature range from -40°C to +125°C
