Diodes Incorporated has actually launched the AP64350Q/AP64351Q/AP64352Q collection of automotive-compliant, 3.5 A, simultaneous dollar converters for POL applications. The converters incorporate a low quiescent existing with a vast input voltage variety in between 3.8 V to 40V. The tools have actually been produced for employment in vehicle applications covering infotainment systems, instrument collections, telematics, ADAS, and also ahead lighting.[map80 4002]

With a totally integrated 75mOhm high-side power MOSFET and also 45mOhm low-side power MOSFET, the gadget supplies high-efficiency step-down DC-DC conversion. The layout of the gadget's entrance drive/bootstrap enables the tools to run in LDO mode, giving near 100% responsibility cycle.

To improve efficiency as the load present nears zero, the gadgets go into PFM, leading to a quiescent current of just 22μA. They additionally give regularity spread range with a changing frequency jitter of ± 6% and an exclusive gate driver system, which reduces high frequency radiated EMI noise created by MOSFET switching.

The devices have distinct more function collections that optimise performance in a little varying methods. The AP64350Q and AP64352Q have an adjustable switching regularity (100kHz-2.2 MHz) and also can be synchronised to an exterior clock. This gives the layout flexibility to produce a choice of low frequency with incredibly high efficiency or high frequency for small form factor options whose switching frequency is outside the AM band. The AP64351Q as well as AP64352Q supply programmable soft-start, which lowers in-rush currents, while the AP64350Q and also AP64351Q give outside payment to optimize loop reaction.[maba 007159]

The gadgets are certified to AEC-Q100 Quality 1, assistance PPAP paperwork, and are manufactured in IATF 16949 accredited centers.
