TI – Simple, easy-to-use, 4A synchronous step-down converter (TPS564201)

Texas Instruments' TPS564201 is an easy-to-use 4A synchronous buck converter in a SOT23 package. The device is optimized to operate with a minimum number of external components and also enables low standby current. These switching power supplies use D-CAP2 mode control to provide fast transient response and support low equivalent series resistance output capacitors (such as specialty polymers) and ultra-low ESR ceramic capacitors without the need for external compensation components. The device operates in pulse skip mode and maintains high efficiency during light load operation. It is available in a 6-pin 1.6mm x 2.9mm SOT (DDC) package and is rated for junction temperature ranging from –40C to 125C.
