Buck变换器问题 |
| 作者：apotato 栏目：电源技术 |
问个弱弱的问题，Buck变换器一般都用什么模拟控制器输出pwm? 那位大虾指点小弟一下：） |

如果是输出PWM，用单片机或者振荡电路就可以了。 如果是选择Buck变换器，下面有很多种。 ISL6525 -- Buck and Synchronous-Rectifier Pulse-Width Modulator (PWM) Controller ISL8105 -- 1V to 12V SINGLE-Phase Synchronous Buck Converter PWM Controller with Integrated MOSFET Gate Drivers ISL8105A -- 1V to 12V SINGLE-Phase Synchronous Buck Converter PWM Controller with Integrated MOSFET Gate Drivers ISL6522A -- Buck and Synchronous Rectifier Pulse-Width Modulator (PWM) Controller ISL6520B -- SINGLE Synchronous Buck Pulse-Width Modulation (PWM) Controller HIP6604B -- Synchronous Rectified Buck MOSFET Drivers HIP6006 -- Buck and Synchronous-Rectifier Pulse-Width Modulator (PWM) Controller ISL6535 -- Synchronous Buck Pulse-Width Modulator (PWM) Controller ISL8104 -- Synchronous Buck Pulse-Width Modulator (PWM) Controller ISL6420 -- ADVANCED SINGLE Synchronous Buck Pulse-Width Modulation (PWM) Controller HIP6012 -- Buck and Synchronous-Rectifier Pulse-Width Modulator (PWM) Controller ISL6540A -- SINGLE-Phase Buck PWM Controller with Integrated High Speed MOSFET Driver and Pre-Biased Load Capability HIP6603B -- Synchronous Rectified Buck MOSFET Drivers ISL6545A -- 5V or 12V SINGLE Synchronous Buck Pulse-Width Modulation (PWM) Controller ISL6545 -- 5V or 12V SINGLE Synchronous Buck Pulse-Width Modulation (PWM) Controller ISL6209 -- High Voltage Synchronous Rectified Buck MOSFET Driver ISL6520 -- SINGLE Synchronous Buck Pulse-Width Modulation (PWM) Controller HIP6602B -- DUAL Channel Synchronous Rectified Buck MOSFET Driver ISL6527 -- SINGLE Synchronous Buck Pulse-Width Modulation (PWM) Controller ISL6594D -- ADVANCED Synchronous Rectified Buck MOSFET Drivers with Protection Features HIP6601B -- Synchronous Rectified Buck MOSFET Drivers ISL6527A -- SINGLE Synchronous Buck Pulse-Width Modulation (PWM) Controller ISL6594B -- ADVANCED Synchronous Rectified Buck MOSFET Driver with Protection Features ISL6406 -- SINGLE Synchronous Buck Pulse-Width Modulation (PWM) Controller HIP6302V -- Microprocessor CORE Voltage REGULATOR Multiphase Buck PWM Controller ISL6594A -- ADVANCED Synchronous Rectified Buck MOSFET Driver with Protection Features ISL6526 -- SINGLE Synchronous Buck Pulse-Width Modulation (PWM) Controller ISL6520A -- SINGLE Synchronous Buck Pulse-Width Modulation (PWM) controller ISL6520A ISL6526A -- SINGLE Synchronous Buck Pulse-Width Modulation (PWM) Controller ISL6439 -- SINGLE Sync Buck PWM Controller for Broadband Gateway Applications |
