As a pin-compatible upgrade to the industry-standard ICL7660, it features 96% power efficiency, 20mA output current, and a boost pin that increases oscillator frequency to 35kHz for smaller capacitor values. Supports both voltage inverting and doubling modes.","working_principle":"The TC7662B uses a switched-capacitor charge pump. Internal switches connect a 'flying' capacitor alternately to the input (charging phase) and to the output with reversed polarity (transfer phase). The on-chip oscillator drives the switching at 10kHz (35kHz with boost). In inverting mode, the output is -VIN. In doubling mode, the output is +2VIN. The conversion is performed without inductors, eliminating EMI concerns.","pin_description":"
