DESCRIPTION

The SG3525A series of pulse width modulator inte-

grated circuits are designed to offer improved per-

formance and lowered external parts count when

used in designing all types of switching power sup-

plies. The on-chip + 5.1 V reference is trimmed to ±

1 % and the input common-mode range of the error

amplifier includes the reference voltage eliminating

external resistors. A sync input to the oscillator al-

lows multiple units to be slaved or a single unit to be

synchronized to an external system clock. A single

resistor between the C_Tand the discharge terminals

provide a wide range of dead time ad- justment.

These devices also feature built-insoft-startcircuitry

with only an external timing capacitor required. A

shutdown terminal controls both the soft-start circu-

ity and the output stages, providing instantaneous

turn off through the PWM latch with pulsed shut-

down, as well as soft-start recycle with longer shut-

down commands. These functions are also control-

led by an undervoltage lockout which keeps the out-

puts off and the soft-start capacitor discharged for

sub-normal input voltages. This lockout circuitry in-

cludes approximately 500 mV of hysteresis for jitter-

free operation. Another feature of these PWM cir-

cuits is a latch following the comparator. Once a

PWM pulses has been terminated for any reason,

the outputs will remain off for the duration of the pe-

riod. The latch is reset with each clock pulse. The

output stages are totem-pole designs capable of

sourcing or sinking in excess of 200 mA. The

SG3525A output stage features NOR logic, giving a

LOW output for an OFF state.
