TK65018 ADVANCED INFORMATION ADVANCED INFORMATION CMOS SWITCHED CAPACITOR VOLTAGE CONVERTER WITH REGULATOR APPLICATIONS FEATURES ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Regulated Output to 2 % 5 mA Output Current Operating Range 1.8 to 8 V Enable Pin Miniature Package (SOT-23L-6) Standby Current (2 µA) Voltage Inverter Negative Voltage Doubler Voltage Regulator Positive Voltage Doubler DESCRIPTION The TK65018 is a monolithic switched capacitor converter with regulation. With just two capacitors, the TK65018 can create a negative voltage supply with regulation. TK65018 With no external timing elements, the converter will selfoscillate at 166 kHz, nominal. ENABLE VIN 20 P Quiescent current is typically 50 µA. Standby current is guaranteed less than 2 µA over the full operating temperature and input voltage ranges. VOUT CLO GND CHI The TK65018 is available in miniature SOT-23L-6 surface mount package. Customized levels of output voltages are available. The TK65018 is available with the following output voltages: -5.0 V, -4.1 V, -3.5 V, -3.0 V, -2.1 V, -1.5, -0.5 V.
