DI-132 - 1.75 W, High Efficiency, Linear Charger Replacement

Overview

Design Highlights SO-8 package enables high switching frequency (100 kHz) on a small PCB (1.12 × 0.89 inches) Enables low component count designs using small, lightweight transformers (EE-13): only 16 components Output power level and MOSFET current Limits allow MOSFET drain node to remain Clampless™ half-wave rectification Allows use of input conducted EMI in Filterfuse™ configuration Filter inductor meets CEC 2008 active mode efficiency standards (minimum requirements are 64% and 55%) No-load input power consumption at 230 VAC <100 mW Meets CISPR-22/EN55022 B without Y capacitor Conducted EMI Limited Constant Voltage/Constant Current (CV/CC) Output characteristics ideal for replacing 50/60 Hz transformer based chargers

What is the difference between a current limiting resistor and a voltage dividing resistor?
[p=28, 2, left][font=微软雅黑,][size=3][color=#000000][backcolor=white]There is no difference in appearance, they are all resistors. Voltage division and current limiting are based on specific scenarios.
