汽车用电流模式 PWM 控制器

CS2841B 提供实施离线固定频率电流模式控制所需的所有必要特性，且外部组件极少。CS2841B（CS-2843A 的变体型号）专用于汽车运行。8.0V（典型值）的低启动阈值电压和耐受 40V 汽车负载转储瞬变的能力对于汽车子系统设计至关重要。CS-2841 系列长期在汽车应用中提供优质性能和高可靠性。CS2841B 结合了一个精确温度控制振荡器，带有内部微调放电电流，可最大程度减少频率波动。还可实现大于 50% 的占空比。板上逻辑可确保启用输出级之前 VREF 得以稳定。离子注入电阻提供更严格的欠压锁定控制。 • Optimized for Off-line Control\n• Internally Trimmed Temperature Compensated Oscillator\n• Maximum Duty-cycle Clamp\n• VREF Stabilized before Output Stage Enabled\n• Low Start-up Current\n• Pulse-by-pulse Current Limiting\n• Improved Undervoltage Lockout\n• Double Pulse Suppression\n• 1% Trimm;
