Additional Infomation About Product

iW3628 Product Summary Off-Line Digital Power Controller for LED Driver with High Power Factor and Low-Ripple Current 1.0 Features 2.0 Description All-in-one non-dimmable low-cost off-line LED driver The iW3628 is a high performance, single-stage AC/DC (isolated and non-isolated applications) power controller for LED luminaires with power factor (PF) correction. The device uses digital control technology to Supports universal input voltage range (90V to 277V ) AC AC build unique hybrid mode control in PWM flyback power and output power up to 20W supplies to achieve high power factor meanwhile minimizing High power factor (PF) with low current-ripple control LED current ripple. This distinctive control approach enables technology the capability for users to make trade-offs between PF and LED current ripple in a single-stage design. It can User-configurable power factor setting (>0.7 to >0.9) achieve excellent LED current regulation over line and load User-configurable over-temperature protection (OTP) variation, without the need for secondary feedback circuit. with temperature-current derating The built-in temperature sensor along with control logic can automatically adjust output current in real-time without Very tight LED current regulation (5%) across line and visible flicker during the process. The iW3628 operates in load, and within primary inductance tolerance (20%) quasi-resonant mode to provide high efficiency along with a Isolated design without opto-coupler number of key built-in protection features while minimizing the external component count, simplifying EMI design, and Supports wide range of LED numbers with tight current lowering the total bill of material cost. It also eliminates the regulation need for loop compensation components while maintaining Stabilized LED current-ripple control without visible stability over all operating conditions. The built-in power limit shimmer or flicker function enables optimized transformer design in universal off-line applications with input voltage from 90V to 277V . AC AC Active start-up scheme enables fastest possible start-up Dialogs innovative proprietary technology maximizes the iW3628 72kHz maximum PWM switching frequency with quasi- performance in a thermal-enhanced SOIC-8 package. The resonant operation iW3628 offers two multi-function pins allowing users to Dynamic base current control to drive low-cost BJT configure PF and OTP as required with no cost or size impact, thereby providing design flexibility. The active start- EZ-EMI design enhances manufacturability up scheme enables the shortest possible start-up time Built-in single-point fault protection features: LED open-/ without sacrificing active efficiency. short-circuit protection and over-current protection No audible noise over entire operating range 3.0 Applications Solid-state LED lighting L LED lighting ballast V OUT- + N V OUT+ U1 iW3628 4 OUTPUT V 8 CC + 5 7 CS/PF ASU 1 6 GND FB/OTP 2 GND 3 GND Figure 3.1: iW3628 Typical Application Circuit (Non-Isolated Application) iW3628 Rev. 1.2 Product Summary 1 of 5 2014 Dialog Semiconductor (UK) Ltd.
