替代MP4560样品可以直接联系德立盛，可以免费提供MP4560替代样品做兼容替代测试。
 The DR5121 is a current mode monolithic buck  switching regulator. Operating with an input range  of 4.5V~60V, the DR5121 delivers 2A of  continuous output current with an integrated high side N-Channel MOSFET. At light loads, the  regulator operates in low frequency to maintain  high efficiency and low output ripple　低输出纹波. Current  mode control 电流模式控制provides tight load transient  response and cycle-by-cycle current limit. The DR5121 guarantees robustness with  short-circuit protection, thermal protection,  current run-away protection, and input under  voltage lockout. The DR5121 is available in 8-pin ESOP封装 and  10-pin EMSOP package, which provides a  compact solution with minimal external  components　并只需要非常少的外围元件.
