The ADP5020 is a highly integrated power management unit with two buck converters, an LDO and I²C control for imaging modules.
The ADP5020 provides a compact power solution for digital imaging modules, integrating two step‑down DC‑DC converters, a low‑dropout regulator, and a power‑sequence controller. It operates from 2.4 V to 5.5 V and can be programmed via an I²C interface or an enable pin.
Key features include a 3 MHz switching frequency, low standby current (1 µA), synchronous buck converters (600 mA and 250 mA), and a 150 mA LDO. The device is supplied in a 20‑lead LFCSP package (4 mm × 4 mm) and supports a wide temperature range from –40 °C to +125 °C.
