UC1525B-SP 稳压脉宽调制器
The UC1525B pulse width modulator integrated circuit is 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 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. These devices also feature built-in soft-start circuitry with only an external timing capacitor required.
