描述 Description
The UC1843 family of control devices 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 under-voltage lockout featuring start up current less than 1 mA, 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. The output stage, suitable for driving N-Channel MOSFETs, is low in the off state. The under-voltage lockout threshold is 8.4 V and maximum duty cycle range is around 100%.
特性 Features
? QML-V Qualified, SMD 5962-86704
? Rad-Tolerant: 50 kRad (Si) TID (ELDRS Free)
? Controlled Baseline
? Optimized For Off-line and DC-to-DC Converters
? Low Start-Up Current (O Error Amp
Radiation tolerance is a typical value based upon initial device qualification with dose rate = 10 mrad/sec. Radiation Lot Acceptance Testing is available - contact factory for details.
