Description
STMICROELECTRONICS UC2843BD1 Current Mode PWM, 30V supply, 500 kHz, 5V/1A out, SOIC-8The UC2843BD1 is a high performance current mode PWM Controller IC. It is 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
- Trimmed oscillator for precise frequency control
- 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
