The TMI3181D is 1.2MHz switching frequency, 3μA ultra-low quiescent current, current mode buck converter with small DFN1.6x1.6-6 package. TMI3181D has a wide input voltage range from 2.5V to 6.5V. The device adopts peak current mode control, the output voltage can be adjusted from 0.6V to input voltage. They have fast load transient response. The 1.2MHz high switching frequency minimizes
the size of external components while keeping low switching losses. They have two operating modes, PWM control and PFM mode switching control in different load condition, and allowing high efficiency over a larger load range.
