Описание

The UC3842BN is a high performance current mode PWM Controller IC provides the necessary features to implement off-line or DC to DC fixed frequency current mode control schemes with a minimal external parts count. Internally implemented circuits include a trimmed oscillator for precise DUTY CYCLE CONTROL under voltage lockout featuring start-up current less than 0.5mA, a precision reference trimmed for accuracy at the error amp input, logic to insure latched operation, a PWM comparator which also provides current limit control and a totem pole output stage designed to source or sink high peak current.

• Trimmed oscillator for precise frequency control
• Oscillator frequency guaranteed at 250kHz
• Current mode operation to 500kHz
• Automatic feed forward compensation
• Latching PWM for cycle-by-cycle current limiting
• Internally trimmed reference with under-voltage lockout
• High current totem pole output
• Under voltage lockout with hysteresis
• Low start-up and operating current
