FEATURES
s s s s s Wide Operating Voltage Range: 1.5V to 15V Boost Pin (Pin 1) for Higher Switching Frequency High Power Efficiency is 96% Easy to Use – Requires Only 2 External Non-Critical Passive Components Improved Direct Replacement for Industry Standard ICL7660 and Other Second Source Devices GENERAL DESCRIPTION
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 TC7662B is available in both 8-pin DIP and 8-pin small outline (SO) packages in commercial and extended temperature ranges. APPLICATIONS
