Описание

The SG2525AN is a Pulse Width Modulator (PWM) designed to offer improved performance and lowered external parts count when used in designing all types of switching power supplies. The on-chip 5.1V 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 adjustment. These devices also feature built-in soft-start circuitry with only an external timing capacitor required. A shutdown terminal controls both the soft-start circuitry and the output stages, providing instantaneous turn off through the PWM latch with pulsed shutdown, as well as soft-start recycle with longer shutdown commands.

• Separate oscillator sync terminal
• Adjustable deadtime control
• Internal soft-start
• Pulse-by-pulse shutdown
• Input undervoltage lockout with hysteresis
• Latching PWM to prevent multiple pulses
• Dual source/sink output drivers
