Description : Dynamic Headroom Controller with Thermal Control Interface and Individual Channel Dimming Control

DESCRIPTION
The LM3463 is a six channel linear LED driver with Dynamic Headroom Control (DHC) interface that is specialized for high power LED lighting applications. The variation of the output current of every output channel in the temperature range of -40°C to 125°C is well controlled to less than ±1%. The output current of every channel is accurately matched to each other with less than ± 1% difference as well.
By interfacing the LM3463 to the output voltage feedback node of a switching power supply via the DHC interface, the system efficiency is optimized automatically. The dynamic headroom control circuit in the LM3463 minimizes power dissipation on the external MOSFETs by adjusting the output voltage of the primary switching power supply according to the changing forward voltage of the LEDs. Comprising the advantages of linear and switching converters, the LM3463 delivers accurately regulated current to LEDs while maximizing the system efficiency.
The dimming control interface of the LM3463 accepts both analog and PWM dimming control signals. The analog dimming control input controls the current of all LEDs while the PWM control inputs control the dimming duty of output channels individually.

Part Name(s) : NTE1753 NTE-Electronic
NTE Electronics
Description : Integrated Circuit Pulse Width Modulator (PWM) Control Circuit

Description:
The NTE1753 is a fixed–frequency pulse width modulation control circuit in a 14–Lead DIP type pack age incorporating the primary building blocks required for the control of a switching power supply.
Output pulse width modulation is accomplished by comparison of the positive sawtooth waveform across capacitor CT to either of two control signals. The output is enabled only during that portion of time when the sawtooth voltage is greater than the control signals. Therefore, an increase in control–signal amplitude causes a corresponding linear decrease of output pulse width.
The control signals are external inputs that can be fed into the dead–time control, the error amplifier inputs, or the feed–back input. The dead–time control comparator has an effective 120mV input offset which limits the minimum output dead time to approximately the first 4% of the sawtooth–cycle time. This would result in a maximum duty cycle of 96%. Additional dead time may be imposed on the output by setting the dead time–control input to a fixed voltage, ranging between 0 to 3.3V.

Features:
• Complete Pulse Width Modulation Control Circuitry
• On–Chip Oscillator with Master or Slave Operation
• On–Chip Error Amplifiers
• On–Chip 5.0 Volt Reference
• Adjustable Dead Time Control
• Uncommitted Output Transistor for 200mA Source or Sink

Description : PULSE-WIDTH-MODULATION CONTROL CIRCUITS

description/ordering information
The TL598 incorporates all the functions required in the construction of pulse-width-modulated (PWM) controlled systems on a single chip. Designed primarily for power-supply control, the TL598 provides the systems engineer with the flexibility to tailor the power-supply control circuits to a specific application.
The TL598 contains two error amplifiers, an internal oscillator (externally adjustable), a dead-time control (DTC) comparator, a pulse-steering flip-flop, a 5-V precision reference, undervoltage lockout control, and output control circuits. Two totem-pole outputs provide exceptional rise- and fall-time performance for power FET control. The outputs share a common source supply and common power ground terminals, which allow system designers to eliminate errors caused by high current-induced voltage drops and common-mode noise.
The error amplifier has a common-mode voltage range of 0 V to VCC − 2 V. The DTC comparator has a fixed offset that prevents overlap of the outputs during push-pull operation. A synchronous multiple supply operation can be achieved by connecting RT to the reference output and providing a sawtooth input to CT.
The TL598 device provides an output control function to select either push-pull or parallel operation. Circuit architecture prevents either output from being pulsed twice during push-pull operation. The output frequency
