TC7662BEOA713

Manufacturer Name: Microchip

Category(s): DC / DC Inductorless Charge Pumps

Description:

Charge Pump INV -15V to -1.5V 20mA 8-Pin SOIC N T/R The TC7662 is a pin-compatible upgrade to the Industry standard TC7660 charge pump voltage converter. It converts a +1.5V to +15V input to a corresponding – 1.5 to – 15V output using only two low-cost capacitors, eliminating inductors and their associated cost, size and EMI. The on-board oscillator operates at a nominal frequency of 10kHz. Frequency is increased to 35kHz when pin 1 is connected to V+, allowing the use of smaller external capacitors. Operation below 10kHz (for lower supply current applications) is also possible by connecting an external capacitor from OSC to ground (with pin 1 open). The TC7662 is available in both 8-pin DIP and 8-pin small outline (SO) packages in commercial and extended temperature ranges.
