LM20123LM20123 3A, 1.5MHz PowerWise Synchronous Buck Regulator January 16, 2008 LM20123 3A, 1.5MHz PowerWise Synchronous Buck Regulator General Description The LM20123 is a full featured 1.5 MHz synchronous buck regulator capable of delivering up to 3A of continuous output current. The current mode control loop can be compensated to be stable with virtually any type of output capacitor. For most cases, compensating the device only requires two external components, providing maximum flexibility and ease of use. The device is optimized to work over the input voltage range of 2.95V to 5.5V making it suited for a wide variety of low voltage systems. The device features internal over voltage protection (OVP) and over current protection (OCP) circuits for increased system reliability. A precision ena……
