ST1843中文资料抗辐照电流模式PWM控制器数据手册ST规格书
ST1843规格书详情
描述 Description
The ST1843 and ST1845 ICs are rad-hard current mode PWM controllers providing an industry standard solution for the implementation of off-line or DC to DC fixed-frequency current mode control schemes with a minimal external part count.
Its radiation hardness, hermetic packaging and its ESCC qualification make it an ideal choice for aerospace and other harsh environments.
特性 Features
• Oscillator frequency guaranteed at 250 kHz
• Trimmed oscillator for precise frequency control
• Current mode operation to 500 kHz automatic feed forward compensation
• Latching PWM for cycle-by-cycle current limiting
• Internally trimmed reference with undervoltage lockout
• High current totem pole output
• Undervoltage lockout with hysteresis
• Low start-up (
