Description
The BCT3752 is a high frequency.
asynchronous boost converter. The internal
MOSFET can support up to 8 White LEDs for
backlighting and OLED power application, and
the internal soft start function can reduce the
inrush current. The device operates with
600kHz fixed switching frequency to allow small
external components and to simplify possible
EMI problems. For the protection, the BCT3752
provides up to 40V OVP to allow inexpensive
and small-output capacitors with lower voltage
ratings. The LED current is initially set with the
external sense resistor RSET. The BCT3752 is
available in TSOT-23-6 packages to save PCB
space.
