The UC2842AM of control ICs provides all the necessary features to implement off-line fixed-frequency, current-mode switching power supplies with a minimum of external components. The current mode architecture demonstrates improved load regulation, pulseby-pulse current limiting and inherent protection of the power supply output switch.
• Low start-up current. (0.5ma max.)
• Trimmed oscillator discharge current
• Optimized for off-line and dc-to-dc converters
• Automatic feed-forward compensation
• Pulse-by-pulse current limiting
• Low-Cost Push-Pull and Half-Bridge Applications
• Telecom dc-to-dc Converters
• Point-of-Load or Point-of-Use Power Modules
• Automotive PSU
• Battery-operated PSU
