General Description
The G5916 is a charge pump for high-current white
LED driving used in camera flash applications. The
architecture of two bucket capacitors is used to de-
crease the output ripple and provides low EMI solution
compared to inductive DC-DC regulators.
The G5916 has independent flash/torch/shutdown
modes. The G5916 is capable to output 500mA of re-
gulated current in flash mode for the duration greater
than 500ms. While driving 700mA output current, the
reduced duration is limit by G5916’s over-temperature
protection. There is a one second safety timer in this
mode to avoid LED damage caused by overheat. The
G5916 can outputs 20% of flash mode current con-
tinuously in torch mode. The flash mode has priority
over the torch mode.
A resistor connected to ISET pin, which is in series
with the LED, is to set the current. The ISET voltage is
250mV and 50mV in flash and torch mode respec-
tively.
The G5916 is available in tiny 10-pin 3x3mm TDFN
package.
