The device is optimized to operate with minimum external component count and also optimized to achieve low standby current. These switch mode power supply (SMPS) devices employ D-CAP2 mode control providing a fast transient response and supporting both low- equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components. The TPS564201 operates in pulse skip mode, maintaining high efficiency during light load operation. The TPS564201 is available in a 6-pin 1.6-mm × 2.9- mm SOT (DDC) package, and specified from a –40°C to 125°C junction temperature. Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) TPS564201 DDC (6) 1.60 mm × 2.90 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.
