TSM121 ic equivalent, single chip pwm & housekeeping ic.
which allow safe operation in all conditions, and very high integration. TSM121 integrates two independent Voltage References which are uncommitted to ensure safe Regulat.
The TSM121 integrated circuit incorporates all sensing circuit to regulate and protect from over voltage, under voltage and over current a multiple output power supply (12V, 5V, 3.3V). TSM121 incorporates all the necessary functions for proper PWM ge.
