TCS4226
28V 2A 500KHz ECOT PSM Sync Step-Down Regulator
产品描述
The ‘TCS4226 is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal powerMOSFETs. It offers a very compact solution to provide a 2A continuous output current over a wide input supplyrange, with excellent load and line regulation. ECOT PSM control operation provides very fast transient responseand easy loop design as well as very tight output regulation.The ‘TCS4226 requires a minimal number of readily available, external components and is available in a space savingSOT23-6 package.
