AP3783RCK6TR-G1

AP3783R PRIMARY SIDE REGULATED SWITCHING MODE POWER SUPPLY CONTROLLER Description Pin Assignments The AP3783R is a high frequency, high efficiency and high accuracy switching mode power supply controller to drive power MOSFET for 5V/2A battery charger/adapter applications. The controller regulates the output voltage and current in the primary side by piece-wise Pulse Frequency Modulation (p-PFM) in discontinuous conduction mode (DCM). The system operating frequency reduces linearly from heavy load to light load in each interval of the p-PFM, and enters constant current mode when the load current equals to the maximum system output current. (Top View) Pin 1 Mark The AP3783R provides accurate constant voltage (CV), constant current (CC) and outstanding dynamic performance without requiring an opto-coupler. It also eliminates the need of loop compensation circuitry while maintaining stability. The AP3783R provides valley turn-on function and 3-Segment drive current to improve the power supply EMI performance. The AP3783R also has built-in fixed cable voltage drop compensation (8%, 4% and 2% of nominal system output voltage to meet various cables with different length and gauge) and adjustable line voltage compensation. The AP3783R achieves excellent regulation and high average efficiency, less than 2s startup time for 30mW standby power solution. When AP3783R is used with APR3415, good undershoot and efficiency performances can be achieved. The AP3783R is packaged in SOT26.            Standby and Auxiliary Power Supplies Notes: 6 CPC GND 2 5 DRI VCC 3 4 FB Features  Adapters/Chargers 1 SOT26 Applications  CS    Less than 30mW Standby Power Consumption Meet Efficiency Requirement of COC Trier2 Valley Turn-on to Reduce Switching Loss and Improve EMI Piece-wise Frequency Reduction to Enhance Conversion Efficiency and Suppress Audio Noise Over Voltage Protection (OVP) Over Temperature Protection (OTP) Short Circuit Protection (SCP) with Hiccup 3-Segment Drive Current for Radiative EMI Suppression Operating Frequency Jitter Function for Conductive EMI Suppression Drive MOSFET for 5W to 20W Battery Charger/Adapter Applications SOT26 SMD Package Comply with Level 3 of IPC/JEDEC J-STD033A Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) For automotive applications requiring specific change control (i.e. parts qualified to AEC-Q100/101/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please contact us or your local Diodes representative. https://www.diodes.com/quality/product-definitions/ 1.
