Current Mode Pulse Width Modulator (PWM) Control Circuit
8-PIN DIP
To order >>> NTE7097
Description:
The NTE7096 and NTE7097 are integrated circuits in 8-Lead DIP type packages that incorporate a new precision temperature-controlled oscillator with an internally trimmed discharge current to minimize variations in frequency. A precision duty-cycle clamp eliminates any need for an external oscillator when at, or near, a 50% duty-cycle condition. Duty-cycles greater than 50% are also possible. Special logic ensures that V
ref is stabilized before the output stage is enabled. Ion-implant resistors provide tighter control of under-voltage lockout.
Other features inclue low start-up current, pulse-by-current limiting, and high-current totem pole output for driving capacitive loads, such as the gate of a power MOSFET. The output is low in the off state, consistent with N-channel devices.
Features:
- Optimized for Off-Line Control
- Internally Trimmed Temperature Compensated Oscillator
- Maximum Duty-Cycle Clamp
- Vref Stabilized Before Output Stage is Enabled
- Low Start-Up Current
