Diodes launches high-efficiency low-voltage 3A synchronous step-down converter in line with Automotive Specifications
2022-05-21
Diodes (NASDAQ: diod) announced the launch of ap61300q and ap61302q Synchronous Step-Down converters that meet automotive specifications. These 3A rated devices have a wide input voltage range of 2.4V to 5.5V, which can meet the needs of vehicle load points (POL), which are more simplified and have a higher efficiency level. These devices are optimized for the vehicle's on-board telematics system, ADAS, power supply and infotainment system and instrument components.

Each of the above buck converters includes a 70m Ω high side power MOSFET and a 50m Ω low side power MOSFET, which jointly provide high-efficiency buck DC-DC conversion. Due to the support of fast switching speed, smaller supporting passive components can be specified to reduce the overall bill of materials (BOM) and save space.



Depending on the load conditions, ap61300q and ap61302q can be configured as pulse frequency modulation (PFM) or pulse width modulation (PWM) operation mode (using the enable pin). When in PFM mode, its quiescent current (IQ) is 19 μ A. High efficiency can be maintained even under light load. In addition, its low dropout (LDO) mode allows the output voltage regulation to be maintained when the input voltage is close to the Vout voltage.

Since both ap61300q and ap61302q have constant on time (COT) control function, only a few external components are needed to realize fast instantaneous response, simplify loop stability and reduce output voltage ripple. Therefore, only less PCB area needs to be configured, and the overall production cost can be reduced.

Ap61300q and ap61302q provide SOT563 package, comply with aec-q100 class I standard, pass PPAP, and are manufactured in IATF 16949 certified facilities.
