The UC3843BD1 is a Pulse Width Modulation (PWM) Controller manufactured by STMicroelectronics with 1A current capability, a frequency range of 48kHz to 500kHz and packaged in SO8 (Small Outline 8) flyback case. This Power Management Integrated Circuit (PMIC) is configured with only one control channel, which is required for control of DC-to-DC power conversion and provides improved transient response, power supply measurement, over current protection and supply sequencing. The UC3843BD1 integrates several features, such as on-chip adjustment of peak current limit, a PWM latch designed for short circuit protection and cycle-by-cycle current limiting and protection.
