Low Power, Single Inducor, Buck-Boost, 600mA DC-DC Converter

CS5517T is a miniature Buck-Boost DC-DC converter

with ultra-low power consumption and high efficiency.

applicable to the application scenarios of

double/three dry batteries or single lithium battery. It

effectively prolong the service time of the battery.

can

CS5517T consists of current mode PWM control loop

error amplifier, comparator, power switch and other

modules. The chip can work efficiently and stably in a

wide load range. The input voltage of CS5517T S

1.8V to 5.0V, and the adjustable output voltage is

1.2V to 5V. When the output voltage is 3.3V and the

input voltage is from 2.7V to 4.4V, it can provide

maximum current load of 600mA

CS5517T can set the output voltage by adjusting two

external resistors. C$5517T provides a slim DFN2x2.

8L package is available for customers to choose, and

its rated working temperature range is - 40 C to 85 C.
