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
