Techcode TD1468
The TD1468 is a monolithic, step‐down, switch mode converter with a built‐in power MOSFET. It achieves a 2A peak‐output current over input supply 10V‐60V with excellent load and line regulation. The TD1468 requires a minimal number of readily‐available external components.GENERAL DESCRIPTION
Current‐mode operation provides a fast transient response and eases loop stabilization. Fault condition protections include cycle‐by‐cycle current limiting and thermal shutdown. The TD1468 is available in a ESOP‐8 package.FEATURES
