60V-Rated Synchronous Buck Converters from Diodes Incorporated Bring Enhanced Efficiency to Automotive PoL Applications
March 09 2023 - 10:14AM
Business Wire
Diodes Incorporated (Diodes) (Nasdaq: DIOD) has introduced two
new synchronous buck converters. Targeted at automotive
point-of-load (PoL) applications, the DIODES AP66200Q and DIODES
AP66300Q cover a wide input voltage range – from 3.8V to 60V. This
allows 12V-, 24V-, and 48V-based automotive systems to all be
addressed. Through their integrated power MOSFETs, these devices
deliver high-efficiency step-down conversion in vehicle powertrain,
telematics, infotainment, and lighting systems.
Thanks to their low quiescent current (IQ) of 40μA, the AP66200Q
and AP66300Q meet the <100µA standby requirements associated
with many automotive applications. They are easily configured to
operate in either pulse frequency modulation (PFM) or pulse width
modulation (PWM) modes. When in PFM mode, improved efficiency will
be achieved at light loads. Operation in PWM mode will result in
low ripple across all loads.
Both devices have adjustable switching frequency capabilities
(up to 2.5MHz) and can be synchronized to avoid beat frequency
issues. Engineers have the flexibility to choose between
high-efficiency operation or a smaller system design. Their low
on-state resistance (RDS(ON)) values and enhanced efficiency modes
enable a substantial reduction in internal power dissipation. The
soft-start pin is programmable to reduce inrush current and can be
employed for tracking multiple output voltages.
The AP66200Q and AP66300Q are AEC-Q100 Grade 1 qualified,
manufactured in IATF 16949 certified facilities, and support PPAP
documentation. They are each supplied in compact 16-pin
U-QFN4040-16/SWP (Type UXB) packages and are available at $1.30 and
$1.50 for the AP66200Q and AP66300Q respectively, in 10,000 unit
quantities.
