MAX8607
1MHz PWM Boost Converter for 1.5A White LED Camera Flash
Highest Current, White LED, Step-Up DC-DC for the Brightest Camera Flash Delivers 1.5A Regulated Current with Up to 84% Efficiency
|
Status
Active: In Production.
Description
The MAX8607 white LED boost converter is optimized
for camera flash/strobe applications using high-current
white LEDs. The MAX8607 integrates a 1MHz PWM
boost converter, 1.5A low-dropout (LDO) current regulator,
and logic control circuitry for a space-saving LED
flash design. Two logic inputs control four modes of
operation: shutdown mode reduces the quiescent current
to 0.1µA (typ), movie mode supplies up to 360mA
of LED current for continuous lighting, flash mode supplies
up to 1.5A of LED current for short-duration lighting
during an exposure, and disco mode supplies +5V
(at up to 1A) to external circuits while driving the LED
with a fixed 80mA current.
The internal 1MHz boost converter features an adaptive
control scheme with an internal switching MOSFET and
synchronous rectifier to improve efficiency and minimize
external component count. The MAX8607 is available
in a 14-pin, 3mm x 3mm TDFN package (0.8mm
max height).
