具有宽输入范围、基准容差为 ±3%、工作温度范围为 –55°C 至 125°C 的 PWM 控制器

The TL5001 and TL5001A incorporate on a single monolithic chip all the functions required for a pulse-width-modulation (PWM) control circuit. Designed primarily for power-supply control, the TL5001/A contains an error amplifier, a regulator, an oscillator, a PWM comparator with a dead-time-control i • Complete PWM Power Control\n• 3.6-V to 40-V Operation\n• Internal Undervoltage-Lockout Circuit\n• Internal Short-Circuit Protection\n• Oscillator Frequency . . . 20 kHz to 500 kHz\n• Variable Dead Time Provides Control Over Total Range\n• ±3% Tolerance on Reference Voltage (TL5001A)\n• Availab;
