LM2662 Overview
Key Specifications
Package: SOIC
Mount Type: Surface Mount
Pins: 8
Max Voltage (typical range): 5.5 V
Description
The LM2662/LM2663 CMOS charge-pump voltage converter inverts a positive voltage in the range of 1.5 V to 5.5 V to the corresponding negative voltage. The LM2662/LM2663 uses two low cost capacitors to provide 200 mA of output current without the cost, size, and EMI related to inductor based converters.
Key Features
- 1 Inverts or Doubles Input Supply Voltage
- 3.5-Ω Typical Output Resistance
- 86% Typical Conversion Efficiency at 200 mA
- (LM2662) Selectable Oscillator Frequency: 20 kHz/150 kHz
- (LM2663) Low Current Shutdown Mode
