资料介绍
The ISL97702 represents a high efficiency, boost converter with integrated boost FET, boost diode and input disconnect FET. A dual feedback circuit allows simple switching between two pre-defined output voltages using a single logic input. With an input voltage of 2.3V to 5.5V the ISL97702 has an output capability of up to 50mA at 18V using integrated 500mA switches. Efficiencies are up to 87%. The integrated protection FET is used to disconnect the boost inductor from the input supply whenever an output fault condition is detected, or when the device is disabled. This gives 0 output current in the disabled mode, compared to standard boost converters where current can still flow when the device is disabled. Using the ISL97702 OLED Driver Demo Board Technical Brief June 12, 2006 TB455.0 Introduction To test the demo board, the following procedure must be followed: The complete schematic of the ISL97702 OLED driver Demo Board is shown in Figure 1. In order to use the demo board Shunt JP1 to GND. To enable ISL97702 boost converter. properly, it is necessary to understand the purpose and C……
