A DC/DC buck regulator, the AOZ2295QI-05 from Alpha & Omega, furnishes 12 A of steady output present with a 5.1-V output voltage. Housed in a thermally enhanced 4×4-mm QFN package deal, this compact system helps the 5-V rails in desktop and laptop computer computing programs.
The AOZ2295QI-05 synchronous EZBuck regulator has a large enter voltage vary of 5.5 V to 25 V. It integrates an impartial linear regulator to generate a 5.0-V output (VREG5) from the enter. If the enter voltage is decrease than 5.0 V, the linear regulator operates in low dropout (LDO) mode. When the buck regulator is enabled, the VREG5 is converted to output to save lots of LDO energy consumption.
The fixed on-time structure of the AOZ2295QI-05 gives an ultrasonic mode to ensure the working frequency is above 30 kHz to stop audible noise. It additionally options an on-time extension mode to make sure the 5-V output stays steady. As well as, the half provides a number of safety options, together with LDO regulator undervoltage lockout, cycle-by-cycle present restrict, short-circuit safety, output overvoltage safety, and thermal shutdown.
Obtainable in manufacturing portions with a lead time of 12 weeks, the AOZ2295QI-05 EZBuck regulator prices $1.48 every in a lot of 1000 items.
