Low dropout 4.2V 2A long time dc to dc step down converter dc step down voltage regulator step down adjustable power supply
Description
high current / 5V to 4.2V
The operating frequency is 1.5MHz and the input voltage is 4.3-6.0V.
2000V antistatic ability (human body model).
The body is small and active, only 12*15mm, it can be used for patching, and it can be used as a plug-in (2.54mm pin).
This module is a step-down DCDC converter, the input voltage must be higher than the output voltage, otherwise the expected voltage value will not be obtained.
Typical application cases: industrial control boards, toys, aircraft models, MCU motherboards, home appliances, communication equipment, digital radio, vehicle power, security monitoring, field collection, street lights.
