The devices are optimized to operate with minimum external component counts 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 TPS561201 operates in pulse skip mode, which maintains high efficiency d...
