TPS561208DDCR

TPS561201 and TPS561208 are easy-to-use 1A synchronous buck converters in a SOT-23 package. These devices are optimized to operate with a minimum number of external components while achieving low standby current. These SMPS devices employ D-CAP2 mode control to provide fast transient response and support low-ESR output capacitors such as polymer capacitors and ultra-low ESR ceramic capacitors without external compensation components. The TPS561201 operates in pulse-skip mode to maintain high efficiency during light-load operation. Both the TPS561201 and TPS561208 are available in a 6-pin 1.6×2.9 (mm) SOT (DDC) package, rated for a junction temperature range of -40°C to 125°C.
