单同步降压脉宽调制（PWM）控制器 Single Synchronous Buck Pulse-Width Modulation PWM Controller
The ISL6520B makes simple work out of implementing a complete control scheme for a DC-DC stepdown converter. Designed to drive N-channel MOSFETs in a synchronous buck topology, the ISL6520B integrates the control, output adjustment and monitoring functions into a single 8-Lead
package.
