1 of 6 1 description the IW1830 is a high performance ac/dc power supply control device that uses digital control technology to build peak current mode pwm fyback power supplies. the device includes an internal power mosfet and operates in quasi-resonant mode and includes key built-in protection features. this combination of features and integration simplifes design, improves effciency , reduces emi and lowers the bill of material cost. the IW1830 removes the need for a secondary feedback circuit while achieving excellent line and load regulation. it also eliminates the need for loop compensation components while maintaining stability over all operating conditions. the pulse-by-pulse waveform analysis allows for a loop response that is much faster than traditional solutions, resulting in improved dynamic load response. the built-in power limit function enables optimized transformer design in universal off-line applications and allows for a wide input voltage range. dialogs innovative proprietary technology ensures that power supplies built with the IW1830 can achieve both the highest average effciency and less than 50mw no-load power consumption in the 15w output power range, and have 2 features primaccurate? primary-side feedback eliminates opto-isolators and simplifes design integrated 700v power mosfet tight constant-voltage regulation across line and load range proprietary optimized 79khz maximum pwm switching frequency with quasi-resonant operation achieves best size, effciency and common mode noise no-load power consumption < 50mw at 230v ac along with fast dynamic load response and short turn-on delay in typical 15w adapter applications 3 applications home appliances power adapters for network devices and monitors universal input ac/dc adapters (up to 15w) adaptively controlled soft-start enables fast and smooth start-up for a wide range of capacitive loads (from 330 f to 6,000 f) with output voltage of 12v and above ez-emi ? design enhances manufacturability adaptive multi-mode pwm/pfm control improves effciency built-in single-point fault protections against output short-circuit, output over-voltage and output over- current built-in over-temperature protection (otp) no audible noise over entire operating range IW1830 off-line digital green-mode quasi-resonant pwm controller integrated with power mosfet rev. 1.0 product summary ? 2016 dialog semiconductor www.dialog-semiconductor.com 23-august-2016
