1. Describe

The ADP5135ACPZ-R7 combines three high performance buck regulators (BUCK1, BUCK2, and BUCK3). It provides 24-pin, 4mm x 4mm LFCSP. The high switching frequency of the buck regulator enables miniature Multiple layers of external components and minimized board space. When the MODE pin is set high, the buck regulator operates with Forced Pulse Width Modulation (PWM) mode. when. . . when MODE pin set low, buck regulator operates in PWM mode The mode is only activated when the load is above a predefined threshold. when load current is below this predefined threshold, the regulator operates in Power Save Mode (PSM), improving the light load efficiency. BUCK1 and BUCK2 work synchronously, BUCK3 run out of phase to reduce input capacitor requirements. The voltage regulator in the ADP5135ACPZ-R7 is controlled by a dedicated Enable pin. The default output voltage can be set externally Adjustable version, or factory programmable over a wide range Preset value in fixed voltage version.
