Its step-up topology accepts an input from 2.7 V to 5 V and delivers a regulated output between 4.575 V and 5.425 V across two independent channels, each rated for 750 mA peak flash current. Dimming is controlled over an I²C interface, making it suited for portable devices where the host processor or image sensor manages flash timing and brightness. The part operates over -40°C to 85°C, fitting consumer and industrial handheld equipment. It comes in a 12-WLCSP (2.02 x 1.66 mm) package for space-constrained PCB layouts. ## Switching frequency and inductor selection The ADP1660ACBZ-R7 can be set to switch at either 1.5 MHz or 3 MHz. Running at 3 MHz allows the use of smaller inductors and ceramic capacitors, shrinking the total solution footprint. ## Output current and thermal considerations Each of the two outputs can deliver 750 mA in flash mode. That level of pulsed current through a WLCSP package requires careful thermal layout: the WLCSP bumps conduct heat into the PCB, so multiple vias to a ground plane are necessary to keep junction temperature within limits during repeated flash events. The boost regulator's internal switches handle the current, so no external FET is needed. The output voltage range accommodates one or two series LEDs, depending on their forward voltage. ## Lifecycle and sourcing The ADP1660ACBZ-R7 is listed as Active in production. It is ROHS3 compliant. Availability and current pricing are confirmed at quote time.","metaTitle":"ADP1660ACBZ-R7 LED Driver, DC-DC Boost Regulator","metaDescription":"ADP1660ACBZ-R7 is an active DC-DC boost regulator LED driver from Analog Devices.
