The device requires only three external components to deliver a fixed output of 5V or 12V. These type of devices are commonly used in.The LT1173 is a versatile micropower DC-DC converter. DC-DC Converter ICs are devices designed to convert a source of DC (direct current) from one voltage to another. Please note if this module exists the 1A, module start. When the output current keeps greater than 1.5A (or output power greater than 10W), please add a heat sink on it. This is an LM2596 DC-DC buck converter step-down power module with high-precision potentiometer, capable of driving a load up to 2A with high efficiency.

Til I.The LT1173 consumes just 110♚ supply current at standby, making it ideal for applications where low quiescent current is important. I need to design a dc-dc converter circuit that takes from a lead acid battery 12 volts and gives me a range of voltage between 0, 1.2v, 3.6. According to its datasheet (Rev 1.5) the PWM control circuit can adjust the duty. The LT1173 functions equally well in step-up, step-down or inverting applications.Needless to say, at the heart of the module is a XL4015 chip from XLSEMI ( which is a 180 KHz fixed frequency PWM step-down (buck) DC/DC converter, capable of driving a 5A load with high efficiency, low ripple and excellent line and load regulation.
