Quiescent current is as low as 20\u00b5A when operating in non-switching mode and a typical of 29\u00b5A in PFM mode.<\/p>\n<p>The switching frequency in continuous switching mode is typically 2.5MHz, dropping to 27kHz in ultrasonic mode.<\/p>\n<p>The AP72200 is available in a 20-ball WLCSP package measuring 2.125mm x 1.750mm.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Diodes Incorporated announces the introduction of the AP72200, a high-current synchronous buck\/boost DC-DC converter with integrated high-side and low-side H-Bridge MOSFETs.
