UC3525BDW характеристики
Регулирующий ШИМ, 35В-8В питание, 500кГц, 18В/100мА выход, SOIC-16.
The UC3525BDW is a Pulse Width Modulation (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 buried Zener reference is trimmed to ±0.75% 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. It 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.
