MAXIM INTEGRATED PRODUCTS ICL7660CSA+T DC/DC Fixed Charge Pump Voltage Converter, Inverter & Multiplier 1.5 V to 10 V in, 20mA out, NSOIC-8The ICL7660CSA+T is a monolithic CMOS switched capacitor voltage converter in 8 pin NSOIC package. This device inverts, doubles, divides or multiplies a positive input voltage. It is pin compatible with the industry standard ICL7660 and LTC1044 devices. It operates from 1. 5V to 10V with no external diode over the full temperature range. The ICL7660 delivers 10mA with 0. 5V output drop. The device combines low quiescent current and high efficiency.

The ICL7660 delivers 10mA with 0.5V output drop. The device combines low quiescent current and high efficiency. Oscillator control circuitry and four power MOSFET switches are included on-chip. Typical applications include generating -5V supply from +5V logic supply to power analogue circuitry, personal communications equipment, op-amp power supplies, EIA/TIA-232E and EIA/TIA-562 power supplies, data acquisition systems and panel meters.
- 98% typical power conversion efficiency
- Operating temperature range from 0°C to 70°C
- Supply current of 80µA at TA = +25°C (pins 1 and 7 no connection, LV open)
- No external diode required for higher voltage operation
- Supply voltage range from 1.5V to 3.5V (RL = 10Kohm, LV to GND) & 3V to 10V (RL = 10Kohm, LV open)
- Maximum output resistance of 100 ohm at TA = +25°C (IL = 20mA, fOSC = 5KHz, LV open)
- Oscillator frequency of 10KHz at V+ = 5V
- Voltage conversion efficiency of 99.9%
- Oscillator impedance of 100Kohm at V+ = 5V

Quality
Color: Missouri Tigers, Size: Large
So i got this for my dog who was board and distroying the house and or having anxiety attacks. This was a cheap option and he loved it as a beginner puzzle. The covers slide so easily and don't stick like wooden puzzles. The amount of treat pockets is also great. The dog doesn't care what team it is related to and neither do I. If you are looking to keep your too smart dog entertained, tis is for you.

My dog loves this toy
Color: Iowa Hawkeyes, Size: Standard
I've tried other engagement toys for my dogs but they didn't seem interesting to her. But my mini-Schnauzer loves this toy. She is excited when this toys comes out of the cabinet. It keeps her mind engaged. Easy to clean. Great value for the money.

May Pose Choking Risk
Color: Mississippi State Bulldogs, Size: Standard
As far as the puzzle aspect my dog was not interested but it did entertain him as a chew toy and the base held up pretty good. Take note though, the brown blocks come right off and may pose a choking risk.
