GMT  G2841 DFN3x3-10  0.5A高压DC-DC升压转换器，1.3集成开关

 General Description

The G2841/G2841A is a 1.2MHz/600kHz fixed-frequency
boost regulator designed for high integration, which
integrates a power switch, an I/O isolation switch.
When a short-circuit condition is detected, the isolation
switch opens up to disconnect the output from the input.
As a result, the IC protects itself and the input
source from any pin, except VIN, from being shorted to
ground. The isolation switch also disconnects the output
from input during shutdown to prevent any leakage
current. Other provisions for protection include
0.5A/1.3A peak-to-peak overcurrent protection, programmable
soft start (SS), over voltage protection
(OVP), thermal shutdown, and under voltage lockout
(UVLO).
The IC operates from input supplies including single Li-ion
battery, triple NiMH, and regulated 5V, such as USB output.
The output can be boosted up to 27V. The
G2841/G2841A can provide the supply voltages of OLED,
TFT-LCE bias, 12V and 24V power rails. The output of
G2841/G2841A can also be configured as a current
source to power up to seven WLEDs in flash light applications.
