5 / 20 page LM2664 www.ti.com SNVS005E – NOVEMBER 1999 – REVISED DECEMBER 2014 6.5 Electrical Characteristics MIN and MAX limits apply over the full operating temperature range. Unless otherwise specified: TJ = 25°C, V+ = 5 V, C1 = C2 = 3.3 μF. (1) PARAMETER TEST CONDITIONS MIN(2) TYP(3) MAX(2) UNIT V+ Supply voltage 1.8 5.5 V IQ Supply current No load 220 500 µA ISD Shutdown supply current 1 µA VSD Shutdown pin input voltage Normal operation 2(4) V Shutdown mode 0.8(5) IL Output current 40 mA RSW Sum of the Rds(on)of the four internal IL = 40 mA 4 8 Ω MOSFET switches ROUT Output resistance(6) IL = 40 mA 12 25 Ω fOSC Oscillator frequency See(7) 80 160 kHz fSW Switching frequency See(7) 40 80 kHz PEFF Power efficiency RL (1 k) between GND and OUT 90% 94% IL = 40 mA to GND 91% VOEFF Voltage conversion efficiency No load 99% 99.96% (1) In the test circuit, capacitors C1 and C2 are 3.3-µF, 0.3-Ω maximum ESR capacitors. Capacitors with higher ESR will increase output resistance, reduce output voltage and efficiency. (2) Min. and Max. limits are ensured by design, test, or statistical analysis. (3) Typical numbers are not ensured but represent the most likely norm. (4) The minimum input high for the shutdown pin equals 40% of V+. (5) The maximum input low for the shutdown pin equals 20% of V+. (6) Specified output resistance includes internal switch resistance and capacitor ESR. See the details in Application and Implementation for simple negative voltage converter. (7) The output switches operate at one half of the oscillator frequency, ƒOSC = 2ƒSW.
