3 Description
The LM36010 is an ultra-small LED flash driver that
provides a high level of adjustability. With a total
solution size of 7 mm², it can produce up to 1.5 A of
LED flash current or up to 376 mA of torch current.
The device utilizes a 2-MHz or 4-MHz fixed-
frequency, synchronous boost converter to power the
1.5-A constant current LED source. An adaptive
regulation method ensures the current source
remains in regulation and maximizes efficiency as it
controls the current from 11 mA up to 1.5 A in flash
mode or from 2.4 mA up to 376 mA in torch mode.
Features of the LM36010 are controlled via an I²C-
compatible interface. These features include:
hardware flash (STROBE) and 128 programmable
currents for both flash and movie mode (torch). The
2-MHz or 4-MHz switching frequency, overvoltage
protection (OVP), and adjustable current limit allow
for the use of tiny, low-profile inductors and ceramic
capacitors. The device operates over a –40°C to
+85°C ambient temperature range.
