AP3785TEV1

Universal AC input, PSR & PFM AP3785T 5V-3A Type C EV1 Board User Guide General Description Based on flyback topology, the AP3785T EV1 board is designed to serve as an example for high efficiency, cost-effective & components less, flexible power design consumer home appliance systems and charger adopter application. It works under Pulse Frequency Modulation method & employed with a primary side regulated mode, and operating at a Valley switching on region, offering an extreme lower standby input power consumption. Its output power is rated at 15W with 5.0V-3A. This EV1 board meets DOE VI and CoC Tier 2 energy efficiency requirements. An USB Type C connector is at output side for powering & charging any interface related device & system. Universal AC input type C 5V-3A PSU Specifications (CV & CC mode) Parameter Input Voltage Input standby power Main output Vo / Io Efficiency Total Output Power Protections XYZ Dimension ROHS Compliance Connector type Value 90 to 265VAC Less than 30 mW 5V – 3A >85% 15W OCP, OVP, OLP,OTP 50.40 x 36.0 x 18 mm Yes Type C 3.0 connector Evaluation Board Picture: (will be updated) Key Features             90 ~265VAC universal AC input range No required any Opto-Coupler needed & its switching frequency is at 20Khz ~ 80Khz. The output drawn current will be depended on ender user device, its max current is 3A. By mean of using an integrated within a low Rds-on MosFet APR34309 SR drive IC & as well operating at Valley-on switching mode, so the power supply converting efficiency is improved up to 85% Efficiency. During the burst mode operation, the 10mW low standby input power can be achieved. Very low start-up operating and quiescent currents Soft start during startup process. Provide accurate constant voltage regulation (CV mode) & accurate constant current (CC). Provide the cable drop compensation and adjustable line voltage compensation. Built-in Jittering Frequency function is built in to reduce EMI emission. There is a transformer saturation protection via primary peak current limitation. Internal Auto Recovery OCP, OVP, OLP, OTP Power Protection, cycle by cycle current limit, also within the DC polarity protection Applications   Figure 1: Top View Figure 2: Bottom View Switching AC-DC Adaptor & Charger Power home Appliances systems AP3785 EV1 Rev1 Nov 14 2016 www.diodes.com Page 1 of 12 Universal AC input, PSR & PFM AP3785T 5V-3A Type C EV1 Board User Guide AP3785T (90 VAC ~ 265VAC one outputs 15W Transformer Spec.) 1) L o w p r o f i l e R M 8 C o r e & Bobbin: 6+6 pin 2) Electrical Diagram: 3) Transformer Parameters 1.
