CS2841BEDR14G Datasheet

Current Mode PWM Controllers


The CS2841BEDR14G provides all the necessary features to implement off-line fixed frequency current-mode control with a minimum number of external components. The CS2841BEDR14G (a variation of the CS2843A) is designed specificallyfor use in automotive operation. The low start threshold voltage of 8.0 V (typ), and the ability to survive 40 V automotive load dump transients are important for automotive subsystem designs. The CS2841 series has a history of quality and reliability in automotive applications. The CS2841BEDR14G incorporates a precision temperature-controlled oscillator with an internally trimmed discharge current to minimize variations in frequency. Duty-cycles greater than 50% are also possible. On board logic ensures that VREF is stabilized before the output stage is enabled. Ion implant resistors provide tighter control of undervoltage lockout. CS2841BEDR14G Features •Optimized for Off-Line Control•Internally Trimmed Temperature Compensated Oscillator•Maximum Duty-Cycle Clamp•VREF Stabilized Before Output Stage Enabled•Low Start-Up Current•Pulse-By-Pulse Current Limiting•Improved Undervoltage Lockout•Double Pulse Suppression•1.0 % Trimmed Bandgap Reference•High Current Totem Pole Output•Pb-Free Packages are Available
