About This Product

■Summary

MPQ4263-AEC1 is a buck-boost converter with two built-in low-side MOSFETs (LS-FETs). The device can deliver up to 140W peak output power (POUT) at a given input voltage (VIN) with excellent efficiency. The MPQ4263-AEC1 is ideal for USB power delivery (PD) applications and can interface with external USB PD controllers via an I2C interface. An I2C interface and one-time programmable (OTP) memory provide flexibility in configurable functionality. Fault condition protection includes CC current limiting with high-side (HS) current sensing, output overvoltage protection (OVP), and thermal shutdown (TSD). The MPQ4263-AEC1 requires a minimal number of standard off-the-shelf external components and is available in a QFN-20 (3mm x 5mm) package. Available in AEC-Q100 Grade 1.

■Features and benefits

・140W buck-boost converter with built-in low-side MOSFET (LS-FET) ・Integrated gate driver for high-side power MOSFET (HS-FET) ・Configurable input undervoltage lockout function (UVLO) ・Start-up input voltage (VIN) range from 3.6V to 36V ・1V to 36V output voltage (VOUT) range ・When VOUT> 3.5V, supports VIN dropping by 2.8V ・Up to 98% peak efficiency ・Reference voltage (VREF) range that can be set via I2C: 0.1V to 2.147V with 1mV resolution ・Accurate output CC current limit: ±5%, supports high-side current detection ・Accurate output current (IOUT) monitor (IMON) function - Compliant with USB PD 3.1, EPR AVS, and PPS specifications -Selectable 280kHz, 420kHz, and 580kHz switching frequency (fSW) - Selectable forced pulse width modulation (PWM) mode or automatic pulse frequency modulation (PFM) / PWM mode ・Output bias VCC LDO for high efficiency ・Line drop compensation by RSENS ・I2C, alert, and one-time programmable (OTP) memory ・Enable (EN) Shutdown Passive Discharge
