MAX660EPA Maxim Integrated Products, MAX660EPA Datasheet - Page 3

• Manufacturer Part Number: MAX660EPA
• Description: Charge Pumps CMOS Monolithic Voltage Converter
• Manufacturer: Maxim Integrated Products

Specifications of MAX660EPA

• Function: Inverting, Step Up
• Output Voltage: - 1.5 V to - 5.5 V, 3 V to 11 V
• Output Current: 100 mA
• Maximum Operating Temperature: + 85 C
• Package / Case: PDIP-8 Narrow
• Minimum Operating Temperature: - 40 C
• Mounting Style: Through Hole

All curves are generated using the test circuit of Figure 1
with V+ =5V, LV = GND, FC = open, and T
unless otherwise noted. The charge-pump frequency is
one-half the oscillator frequency. Test results are also
valid for doubler mode with GND = +5V, LV = OUT, and
OUT = 0V, unless otherwise noted; however, the input
voltage is restricted to +2.5V to +5.5V.
