(1) PARAMETER TEST CONDITION MIN(2) TYP(3) MAX(2) UNIT V+ Supply Voltage RL = 1k Inverter, LV = 3.5 5.5 Open V Inverter, LV = GND 1.5 5.5 Doubler, LV = OUT 2.5 5.5 IQ Supply Current No Load FC = V+ (LM2662) 1.3 4 LV = Open SD = Ground mA (LM2663) FC = Open 0.3 0.8 ISD Shutdown Supply Current 10 μA (LM2663) VSD Shutdown Pin Input Voltage Shutdown Mode 2 (4) V (LM2663) Normal Operation 0.3 IL Output Current 200 mA ROUT Output Resistance(5) IL = 200 mA 3.5 7 Ω fOSC Oscillator Frequency(6) OSC = Open FC = Open 7 20 kHz FC = V+ 55 150 fSW Switching Frequency(7) OSC = Open FC = Open 3.5 10 kHz FC = V+ 27.5 75 IOSC OSC Input Current FC = Open ±2 μA FC = V+ ±10 PEFF Power Efficiency RL (500) between V + and OUT 90% 96% IL = 200 mA to GND 86% VOEFF Voltage Conversion Efficiency No Load 99% 99.96% (1) In the test circuit, capacitors C1 and C2 are 47-μF, 0.2-Ω maximum ESR capacitors. Capacitors with higher ESR will increase output resistance, reduce output voltage and efficiency. (2) –40°C to 105°C (3) TJ = 25°C (4) In doubling mode, when Vout > 5 V, minimum input high for shutdown equals Vout − 3 V. (5) Specified output resistance includes internal switch resistance and capacitor ESR. (6) For LM2663, the oscillator frequency is 150 kHz. (7) The output switches operate at one half of the oscillator frequency, ƒOSC = 2ƒSW.
