TC7662BCOA (Microchip) is a charge-pump voltage converter in an SOIC-8 package, commercial temperature range.

• Converts a +1.5 V to +15 V input to a corresponding negative voltage
• 96% power efficiency
• Requires only 2 external non-critical capacitors
• Boost pin for higher switching frequency
• Pin-compatible upgrade to the TC7660
