SG3527A PULSE WIDTH MODULATOR CONTROL CIRCUITS

Transcription

1 The 3525, 3527 pulse width modulator control circuits offer improved performance and lower external parts count when implemented for controlling all types of switching power supplies. The on chip +5. reference is trimmed to ±% and the error amplifier has an input common mode voltage range that includes the reference voltage, thus eliminating the need for external divider resistors. sync input to the oscillator enables multiple units to be slaved or a single unit to be synchronized to an external system clock. wide range of deadtime can be programmed by a single resistor connected between the T and ischarge pins. These devices also feature built in soft start circuitry, requiring only an external timing capacitor. shutdown pin controls both the soft start circuitry and the output stages, providing instantaneous turn off through the PW latch with pulsed shutdown, as well as soft start recycle with longer shutdown commands. The under voltage lockout inhibits the outputs and the changing of the soft start capacitor when is below nominal. The output stages are totem pole design capable of sinking and sourcing in excess of 200 m. The output stage of the 3525 features OR logic resulting in a low output for an off state while the 3527 utilized OR logic which gives a high output when off. 8.0 to 35 Operation 5. ±.0% Trimmed Reference 00 z to 400 kz Oscillator Range eparate Oscillator ync Pin djustable eadtime ontrol Input ndervoltage ockout atching PW to Prevent ultiple Pulses Pulse by Pulse hutdown ual ource/ink Outputs: ±400 m Peak P WIT OTOR OTRO IRIT 6 6 Inv.

This is subject to the added requirement of discharging whatever external capacitance may be attached to these pins. n alternate approach is the use of the shutdown circuitry of Pin 0 which has been improved to enhance the available shutdown options. ctivating this circuit by applying a positive signal on Pin 0 performs two functions: the PW latch is immediately set providing the fastest turn off signal to the outputs; and a 50 µ current sink begins to discharge the external soft start capacitor. If the shutdown command is short, the PW signal is terminated without significant discharge of the soft start capacitor, thus, allowing, for example, a convenient implementation of pulse by pulse current limiting. olding Pin 0 high for a longer duration, however, will ultimately discharge this external capacitor, recycling slow turn on upon release. Pin 0 should not be left floating as noise pickup could conceivably interrupt normal operation OTORO O I I T

13 Packaging Information In rief... The packaging availability for each device type is indicated on the individual data sheets and the elector uide. ll of the outline dimensions for the packages are given in this section. The maximum power consumption an integrated circuit can tolerate at a given operating ambient temperature can be found from the equation: T(max) T P(T) = Rθ(Typ) where: P(T) = Power issipation allowable at a given operating ambient temperature. This must be greater than the sum of the products of the supply voltages and supply currents at the worst case operating condition.
