TL3843BDR 描述

***p One Stop Global: Current Mode PWM Controller 0V to 30V 200mA 14-Pin SOIC T/R

***as Instruments: 30V, 0.2A high Performance 500KHz current mode PWM with 8.4V/7.6V UVLO, 100% duty cycle, 0C to 70C 14-SOIC 0 to 70

***ser: PWM Power Supply Controllers Current Mode PWM Controller

***ark: Pulse Width Modulation (PWM) Controller IC; Frequency:500kHz; No. of Pins:14; Operating Temperature Range:0°C to +70°C; Control Mode:Current; Leaded Process Compatible:Yes; Number of PWM Outputs:1; Output Current:200mA ;RoHS Compliant: Yes

***XS: The TL284xB and TL384xB series of control integrated circuits provide the features that are necessary to implement off-line or dc-to-dc fixed-frequency current-mode control schemes, with a minimum number of external components. Internally implemented circuits include an undervoltage lockout (UVLO) and a precision reference that is trimmed for accuracy at the error amplifier input. Other internal circuits include logic to ensure latched operation, a pulse-width modulation (PWM) comparator that also provides current-limit control, and a totem-pole output stage designed to source or sink high-peak current. The output stage, suitable for driving N-channel MOSFETs, is low when it is in the off state.

***AS INSTR: The TL284xB and TL384xB series are pin compatible with the standard TL284x and TL384x with the following improvements. The start-up current is specified to be 0.5 mA (max), while the oscillator discharge current is trimmed to 8.3 mA (typ). In addition, during undervoltage lockout conditions, the output has a maximum saturation voltage of 1.2 V while sinking 10 mA (VCC = 5 V).

***AS USD: Major differences between members of these series are the UVLO thresholds and maximum duty-cycle ranges. Typical UVLO thresholds of 16 V (on) and 10 V (off) on the TLx842B and TLx844B devices make them ideally suited to off-line applications. The corresponding typical thresholds for the TLx843B and TLx845B devices are 8.4 V (on) and 7.6 V (off). The TLx842B and TLx843B devices can operate to duty cycles approaching 100%. A duty-cycle range of 0% to 50% is obtained by the TLx844B and TLx845B by the addition of an internal toggle flip-flop, which blanks the output off every other clock cycle.The TL284xB-series devices are characterized for operation from -40°C to 85°C. The TL384xB-series devices are characterized for operation from 0°C to 70°C.
