描述 Description

LCD Bias for LCD Display

DW8755A is a DC-DC converter with dual synchronous output, which is a unique and highly
integrated device. It continuously supports maximum 100mA output current. It operates in the
fixed switching frequency of 540KHz. Its various functions protect abnormal operation. It offers
internal softstart and Thermal Shutdown functions. It also has an anti-ringing circuit that can
detect the output ringing noise. It consumes only 1μA when EN pin is disabled. It contains a
true shutdown by inner circuits. It provides an auto discharge circuit optionally.
