Single Chip Pwm & Housekeeping Ic For Half Bridge Smps

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 generation and pulse transformer drive to be adapted easily in the PC SMPS power supplies, and all the Housekeeping features which allow safe operation in all conditions, and very high integration. TSM121 integrates two independent Voltage Ref- erences which are uncommitted to ensure safe Regulation and Protection by the same chip. By STMicroelectronics
