• 1、 Module Introduction This module adopts a 4A switching latest chip scheme, with a maximum input current of up to 2A, steady performance, and a switching frequency of about 1 2MHZ, the module operates in either PWM and PFM operating modes, whereas the empty shipment mild load module operates in PFM mode to lessen static operation When the weight current increases, it robotically adjusts to PWM mode The module makes use of a satisfactory latest inductor to circumvent the problem of limiting the module output thanks to inductance The module adopts a typical BOOST increase structure, so the output terminal is statically short circuited, and the output strength completely depends on the input voltage and latest It is not probable to output 2A current at any voltage said available in the market (refer to the detailed explanation below) The module reserves a jumper pad for 5V9V12V output selection, which allows users to easily alter between the three typical voltages stated above Additionally, an ADJ pad with a 0805 package is also reserved, Users can weld resistors right here to set their desired output voltage 2、 Parameter Introduction Module type: Switching power supply, boost energy supply Input voltage: DC2 (lower than output voltage via 0) Input current: 2A (max) Output current: determined by way of input, calculated according to next instructions Output voltage: DC 5/9/12V Output power: User input voltage x1 five (max) Switching frequency: approximately 1 Working mode: PWM/PFM Quiescent current: 200ua-600ua (PFM mode) Adjustment method: Jumper pad selection, 5/9/12V, ADJ pad adjustable Module interface: solder pad (capable of connecting to two 54mm rows of pins) Module size: 24 x thirteen 7mm (manual measurement with deviation)
