XL7660 – DC-DC Converter (Charge Pump Voltage Converter) – Xinluda

The Xinluda XL7660 is a monolithic CMOS charge pump (switched-capacitor) voltage converter that inverts a +1.5V to +10V supply into a negative output, supplied in an 8-pin SOP-8 package. An industry-standard 7660-family pinout for generating negative rails from a single positive source.

The Xinluda XL7660 is a monolithic CMOS voltage-conversion IC that operates as a charge pump (switched-capacitor) DC-DC converter. It is a member of the widely used 7660 family and is most commonly employed to generate a negative supply rail from a single positive input, requiring only two inexpensive external capacitors. The XL7660 is supplied in a surface-mount SOP-8 package; the pin-compatible XD7660 covers the through-hole DIP-8 footprint.

With a supply range spanning 1.5V to 10V and a low typical no-load supply current, the XL7660 is well suited to battery-powered and low-power analog systems that need a clean negative bias without an inductor-based supply.

Key Features

• Monolithic CMOS charge-pump / switched-capacitor voltage converter
• Operating supply voltage range: 1.5V to 10V
• Inverted output voltage: -1.5V to -10V (voltage inversion mode)
• Typical voltage conversion efficiency: 98%
• Output resistance: approximately 60 ohm
• Typical oscillator frequency: 10 kHz; a frequency-boost pin can raise the switching frequency
• Low typical supply current (microamp class, no load)
• Operating temperature range: -40 C to +85 C
• Requires only two external capacitors for a basic voltage-inverter circuit
• Industry-standard 7660-family pinout; RoHS compliant
• Package: 8-pin SOP-8 (XL7660); pin-compatible DIP-8 available as XD7660

Applications

• Generating negative bias rails (for example -5V from +5V) for op-amps and analog front ends
• Negative supply for data converters, sensors, and instrumentation
• LCD bias and contrast supplies
• Battery-powered and handheld electronics
• Voltage doubling / charge-pump supply circuits
• Test, measurement, and industrial control boards

Why Source XL7660 from Pacific Component Xchange

The Xinluda XL7660 is a value-oriented charge-pump IC with limited authorized-distributor coverage outside of Asia, which can make consistent supply a challenge for production buyers.
