Product Overview
The LM2767 is a Texas Instruments CMOS switched capacitor charge-pump voltage converter intended for voltage-doubler operation over a 1.8 V to 5.5 V input range. In the typical voltage doubler application, the circuit uses two capacitors and one diode, with the diode required for start-up and protection.
Electrical characteristics are specified with C1 = 10 uF and C2 = 10 uF test capacitors with 0.3 ohm maximum ESR. At V+ = 5 V with a 15 mA load, output resistance is 20 ohm typical and 40 ohm maximum. The oscillator runs from 8 kHz to 50 kHz, with 22 kHz typical; the output switches operate at one half of oscillator frequency, giving an 11 kHz typical switching frequency.
The device is offered in a 5-pin SOT-23 DBV package. Pin functions are VOUT, GND, CAP-, V+, and CAP+. Recommended operating conditions cover -40 to 100°C junction temperature and -40 to 85°C ambient temperature, while the device remains always enabled whenever power is applied.
