BCD Semiconductor Manufacturing Limited AP3001
The AP3001 series of regulators are fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 3A load with excellent line and load regulation. These regulators are simple to use and include internal frequency compensation and a fixed frequency oscillator, so that a system adopting AP3001 requires a minimum number of external components to work. These ICs are available in TO-220-5L, TO-220B-5L and TO-263-5L packages.| Part No. | AP3001 |
