Integrated Circuit
Current Mode Pulse Width Modulator (PWM)
Control Circuit
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 mini-
mize variations in frequency. A precision duty–cycle clamp eliminates any need for an external oscil-
lator when at, or near, a 50% duty–cycle condition. Duty–cycles greater than 50% are also possible.
Special logic ensures that V
is stabilized before the output stage is enabled. Ion–implant resistors
ref
provide tighter control of under–voltage lockout.
Other features include 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.
