Description
STMICROELECTRONICS UC3842BN Current Mode PWM Controller, 12V-25V supply, 250kHz, 13.5V/200mA out, DIP-8The 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
- 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
