NTE1729
Integrated Circuit
Pulse Width Modulator (PWM) Control Circuit
Description:
The NTE1729 is an inverter control unit in a 16–Lead DIP type package which provides all the control
circuitry for PWM type switching regulators. Included in this device is the voltage reference, dual error
amplifiers, oscillator, pulse width modulator, pulse steering flip flop, dual alternating output switches,
and dead time control.
Features:
Complete PWM Power Control Circuit
Adjustable Dead Time: 0 to 100%
No Double Pulsing of Same Output during Load Transient Condition
Dual Error Amplifiers have Wide Common Mode Input Voltage Capability: –0.3V to V
CC
–2V
Circuit Architecture Provides Easy Synchronization
Uncommitted Outputs for 250mA Sink or Source
With Miss–Operation Prevention Circuit for Low Level Supply Voltage
