Diodes Incorporated announced the AP64350Q/AP64351Q/AP64352Q series of automotive-compliant, 3.5A, synchronous buck converters for point of load (POL) applications.
The AP6435xQ combines a low quiescent current with a wide input voltage range of 3.8V to 40V. The devices have been developed for use in automotive applications including infotainment systems, instrument clusters, telematics, advanced driver assistance systems (ADAS), and forward lighting.
The AP64350Q, AP64351Q, and AP64352Q have distinct additional feature sets that optimize performance in slightly different ways. The AP64350Q and AP64352Q have an adjustable switching frequency (100kHz – 2.2MHz) and can also be synchronized to an external clock. This provides the design flexibility to deliver a choice of low frequency with extremely high efficiency, or high frequency for small form factor solutions whose switching frequency is outside the AM band. The AP64351Q and AP64352Q have programmable soft-start, which reduces in-rush currents, while the AP64350Q and AP64351Q have external compensation to optimize loop response.
The AP64350Q, AP64351Q, and AP64352Q are qualified to AEC-Q100 Grade 1, support PPAP documentation, and are manufactured in IATF 16949 certified facilities.
