TC1237 - Inverting Dual Charge Pump Voltage Converters
The TC1235/1236/1237 are CMOS dual inverting charge pump voltage converters with a low power shutdown mode in MSOP 10-Pin packages.
Only four external capacitors are required for full circuit implementation.
Switching frequencies are 12kHz for the TC1235, 35kHz for the TC1236 and 125kHz for the TC12
