Brand: Generic
Category: Buck Converter

The LM317 DC-DC converter is an electronic circuit for converting a DC source voltage from one level to a lower level. This module is important in some portable electronic devices such as cell phones and laptops, which are primarily supplied by power from batteries. The step-down voltage can be easily adjusted and is, therefore, more efficient than using multiple batteries to achieve the same thing.

Features :

  1. Output Current: 1.5A (Min.), 2.2A (Typical)
  2. Input-Output Voltage Differential (VI-VO): 40Vdc (Max.)
  3. Voltage Input: 4.2~40V
  4. Adjustable Output Voltage Range: 1.2~37V
  5. Operating Temperature: 0~125 ℃
  6. Current Output: 1.5A
  7. Characteristic Frequency: 100MHz
  8. Input Method: VIN Input Positive Level, GND Input Negative
  9. Output Method: VOUT Output Positive Level, GND Output Negative
