... Power supply unit for LCDs BP5302 / BP5302F The BP5302 and BP5302F are converter units for supplying power to liquid crystal display (LCD) panels. The ICs supply a negative voltage from a positive power supply. They are available in a single in-line package as an upright (BP5302) or L-shaped lead (BP5302F) type ...

... In particular, make sure to mini- mize the impedance between the input-side capacitor (C1) and pin 9. (Reference valve: A length less than 50mm is recom- mended for a copper foil of 1.0mm wide and 35 m thick.) BP5302 / BP5302F (2) Avoid frequent switching using the ON / OFF CTL pin (5 times per second at the maximum). (3) R1 and R2 resistors, which are used for changing the output voltage, are usually not required ...
