Product Overview
LTC660 is a monolithic CMOS switched-capacitor voltage converter. It performs supply voltage conversion from positive to negative from an input range of 1.5V to 5.5V, resulting in complementary output voltages of -1.5V to -5.5V. It also performs a doubling at an input voltage range of 2.5V to 5.5V, resulting in a doubled output voltage of 5V to 11V. Only two external capacitors are needed for the charge pump and charge reservoir functions. The converter has an internal oscillator that can be overdriven by an external clock or slowed down when connected to a capacitor. The oscillator runs at a 10KHz frequency when unloaded. A higher frequency outside the audio band can also be obtained if the BOOST pin is tied to V+. It is used in applications such as conversion of 5V to ±5V supplies, inexpensive negative supplies, data acquisition systems, high current upgrade to LTC1044 or LTC7660.
- Supply current is 0.5mA max at (no load, boost = open, TA = 25°C)
- Oscillator frequency is 10KHz typ at (TA = 25°C)
- Power efficiency is 98% typ at (RL = 1K connected between V + and VOUT)
- Voltage conversion efficiency is 99.96% typ at (TA = 25°C)
- Output current is 100mA min at (VOUT more negative than -4V)
- Oscillator sink or source current is ±1.1µA typ at (Boost = open, TA = 25°C)
- Operating temperature range from 0°C to 70°C
- Package style is 8-lead NSOIC
