AP6450xQ Switching Voltage Regulators

Diodes Incorporated AP6450xQ Switching Voltage Regulators are 40V, 5A, and high-efficiency synchronous DC-DC buck converters qualified to AEC-Q100 grade 1. The regulators fully integrate a 45mΩ high-side power MOSFET and a 20mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion. These AP6450xQ regulators feature a special gate drive/bootstrap design that enables them to operate in LDO mode, with a near 100% duty cycle. The regulators enter Pulse Frequency Modulation (PFM) and automatically enhances efficiency, as the load current approaches zero. The AP6450xQ regulators are easily used by minimizing the external component count due to its adoption of peak current mode control.
