ABSOLUTE MAXIMUM RATINGS

V+ to GND ............................................................. 6V

Input Voltage (Pins 1, 6 and 7) .. -0.3V to (V+ + 0.3V)

BOOST/FC and OSC Input Voltage ........... The least

negative of (Out - 0.3V) or (V+ - 6V) to (V+ + 0.3V)

Output Short-circuit Duration to GND .............. 1 sec.

(OUT may be shorted to GND for 1 sec without damage but

shorting OUT to V+ should be avoided.)

Continuous Power Dissipation (TA = 70

°C)

Plastic DIP ................................................ 730mW

SOIC ......................................................... 500mW

TDFN ............................................................... 1W

Operating Ambient Temperature Range

CAT660E .............. -40

°C to 85°C

Storage Temperature ......................... -65

°C to 160°C

Lead Soldering Temperature (10 sec) ............. 300

°C

Note: TA = Ambient Temperature

These are stress ratings only and functional operation is not

implied. Exposure to absolute maximum ratings for prolongued

time periods may affect device reliability. All voltages are with

respect to ground.

Efficiency

Note 1. In Figure 1, test circuit capacitors C1 and C2 are 150

µF and have 0.2Ω maximum ESR. Higher ESR levels may reduce efficiency and output

voltage.

Note 2. The output resistance is a combination of the internal switch resistance and the external capacitor ESR. For maximum voltage and efficiency

keep external capacitor ESR under 0.2

Ω.

Note 3. FOSC is tested with COSC = 100pF to minimize test fixture loading. The test is correlated back to COSC=0pF to simulate the capacitance

at OSC when the device is inserted into a test socket without an external COSC.

ELECTRICAL CHARACTERISTICS

V+ = 5V, C1 = C2 = 150

µF, Boost/FC = Open, COSC = 0pF, inverter mode with test circuit as shown in Figure 1 unless

otherwise noted. Temperature is over operating ambient temperature range unless otherwise noted.
