UC3843A CURRENT MODE PWM CONTROL IC Description: The UTC UC3843A provides the necessary features to implement offline or DC-to-DC fixed frequency current mode, controlled circuits with minimal external components. Functions • Low starting current (typically 0.12 mA) • Automatic feed-forward compensation • Pulse-by-pulse current limitation • Undervoltage lockout with hysteresis • Dual pulse suppression • High-current totemPole output for direct control of the MOSFET • Internally trimmed band gap reference • 500 kHz operation https://elecena.pl/product/20098041/uc3843a-current-mode-pwm-controller-1-fold-1-aout-30-vcc-dip-8 2022-01-15 https://elecena.pl/product/20098041/uc3843a-current-mode-pwm-controller-1-fold-1-aout-30-vcc-dip-8 2022-10-06 https://elecena.pl/product/20098041/uc3843a-current-mode-pwm-controller-1-fold-1-aout-30-vcc-dip-8 2023-05-14 https://elecena.pl/product/20098041/uc3843a-current-mode-pwm-controller-1-fold-1-aout-30-vcc-dip-8 2023-11-13 https://elecena.pl/product/20098041/uc3843a-current-mode-pwm-controller-1-fold-1-aout-30-vcc-dip-8 2024-06-08 https://elecena.pl/product/20098041/uc3843a-current-mode-pwm-controller-1-fold-1-aout-30-vcc-dip-8 2024-07-08 https://elecena.pl/product/20098041/uc3843a-current-mode-pwm-controller-1-fold-1-aout-30-vcc-dip-8 2025-12-13 https://elecena.pl/product/20098041/uc3843a-current-mode-pwm-controller-1-fold-1-aout-30-vcc-dip-8 2026-01-20 https://elecena.pl/product/20098041/uc3843a-current-mode-pwm-controller-1-fold-1-aout-30-vcc-dip-8 2026-02-12
