onsemi MC1121
The MC1121 is a charge pump converter with 100mA output current capability. It converts a 2.4V to 5.5V input to a corresponding negative output voltage. The oscillator frequency increases to 200kHz when FC is connected to VDD, allowing the use of smaller capacitors.| Part No. | MC1121 |
