Diodes Incorporated announced the AP61100Q, a 5,5 V, 1 A continuous output current, automotive-compliant, synchronous buck converter for point of load (POL) applications.
With a fully integrated 110 mΩ high-side power MOSFET and 80 mΩ low-side power MOSFET, it provides high-efficiency step-down DC-DC conversion from 5 V and 3,3 V input rails. The converter has been developed for use in automotive applications including infotainment systems, instrumentation clusters, telematics and advanced driver assistance systems (ADAS).
The AP61100Q offers design flexibility with a multi-functional programmable EN pin that enables the device to operate in forced pulse width modulation (PWM), where the frequency is constant across all loads, or in pulse frequency modulation (PFM). When in PFM, the AP61100Q delivers up to 89% efficiency at 5 mA light load and a low quiescent current of only 15 μA.
The buck converter has a wide output voltage range of 0,6 V to 3,6 V and operates at 2,2 MHz to avoid AM radio band frequencies. By using constant on-time control, the buck converter can achieve fast transient response, easy loop stabilisation and low output voltage ripple.
The AP61100Q is qualified to AEC-Q100 Grade 1, supports PPAP documentation, and is manufactured in IATF 16949 certified facilities. The device is available in the SOT563 (1,6 mm x 1,6 mm) package.
