NTE1723 - Integrated Circuit Pulse Width Modulator (PWM) Regulator

Description

The NTE1721 and NTE1723 are pulse width modulator control

circuits designed to offer improved performance and lowered external parts count when implemented for controlling all types of switching power supplies.

chip +5.1V reference is trimmed to ±1% and the input common

Features

  • NOR logic resulting in a low output for an off state while the NTE1723 utilizes OR logic which gives a high output when off. Features: D 8V to 35V Operation D +5.1V ±1% Trimmed Reference D 100Hz to 400kHz Oscillator Range D Separate Oscillator Sync Pin D Adjustable Dead Time Control D D D D Input Undervoltage Lockout Latching PWM to Prevent Multiple Pulses Pulse.

NTE1721 & NTE1723 Integrated Circuit Pulse Width Modulator (PWM) Regulator Description: The NTE1721 and NTE1723 are pulse width modulator control–circuits designed to offer improved performance and lowered external parts count when implemented for controlling all types of switching power supplies. The no–chip +5.1V reference is trimmed to ±1% and the input common–mode range of the errror amplifier includes the reference voltage, thus eliminating the need for external divider resistors. A sync input to the oscillator enables multiple units to be slaved or a single unit to be synchronized to an external system clock. A wide range of dead time can be programmed by a single resistor connected between the CT and the Discharge pins.
