Published:2011/4/21 5:51:00 Author:May | Keyword: Improved, switching, power supply module | From:SeekIC

The AC input voltage of small switching power supply module using TOP222P chip is 100~245V. And it is two ways DC output. The largest DC output is 10v800mA(15v800mA)、5v800mA, the total output is less than 15W, power supply efficiency is 6％～85％. (Note 1: the output 5V group of this power module has the function of voltage regulation, another group output voltage can set like: it is 15V when connected with + , it is 10V when connected with 0 ).voltage accuracy: 4%;votlage adjustment rate: 0.7%;5V load adjustment rate: 1%;10V load adjustment rate: 8%;or 15V load adjustment rate: 10%;The size of small power supply module: length is 46mm, width is 28mm, height is 20mm.parts lists of small power supply module name quantityTOP222P chip 1EE19 transformer 1UF4007diode 1PC817 opto-coupler 13.3UH bead 23.6 voltage regulator diode 1471 voltage dependent resistor 110UF/400V electrolysis 1102/1KV ceramic chip 1470UF/25V electrolysis 1470UF/25V electrolysis 147UF/25V electrolysis 1100UF/25V electrolysis 1UF4004 diode 2IN4148 diode 1(can replace by UF4004 diode)1N4007diode 433/1W resistor 156K/0.25W resistor 110/0.25W resistor 1100/0.25W resistor 11K/0.25W resistor 13mmLED 1circuit wafer 1
