Description
The SG3525A series of pulse width modulator integrated circuits are designed to offer improved
performance and lowered external parts count when used in designing all types of switching power
supplies. 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 allows multiple units to be slaved or a single unit to be synchronized to an external system
clock. A single resistor between the CT and the discharge terminals provide a wide range of dead time
ad- justment. These devices also feature built-in soft-start circuitry with only an external timing capacitor
required. A shutdown terminal controls both the soft-start circuity 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 circuits 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 period. 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.
