iW1830
Off-Line Digital Green-Mode Quasi-Resonant
PWM Controller Integrated with Power MOSFET
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 flyback 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 simplifies design, improves efficiency, 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.
Dialog’s innovative proprietary technology ensures that power supplies built with the iW1830 can achieve both the
highest average efficiency 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 simplifies design
●● Integrated 700V power MOSFET
●● Tight constant-voltage regulation across line and load
range
●● Adaptively controlled soft-start enables fast and
smooth start-up for a wide range of capacitive loads
(from 330μF to 6,000μF) with output voltage of 12V
and above
●● EZ-EMI® design enhances manufacturability
●● Adaptive multi-mode PWM/PFM control improves
●● Proprietary optimized 79kHz maximum PWM switching
efficiency
frequency with quasi-resonant operation achieves best
size, efficiency and common mode noise
●● Built-in single-point fault protections against output
short-circuit, output over-voltage and output over●● No-load power consumption < 50mW at 230VAC along
current
with fast dynamic load response and short turn-on
delay in typical 15W adapter applications
●● Built-in over-temperature protection (OTP)
3 Applications
●● No audible noise over entire operating range
●● Home appliances
●● Power adapters for network devices and monitors
●● Universal input AC/DC adapters (up to 15W)

WARNING:
The iW1830 is intended for high voltage AC/DC offline applications. Contact with live high voltage offline
circuits or improper use of components may cause lethal or life threatening injuries or property damage.
Only qualified professionals with safety training and proper precaution should operate with high voltage
offline circuits.

convection chamber with 1W dissipated power.
Note 2.
ψJB [Psi Junction to Board] provides an estimation of the die junction temperature relative to the PCB [Board] surface
temperature. ψJ-MOSFET [Psi Junction to Drain pin] provides an estimation of the die junction temperature relative to the
Drain pin [internal MOSFET Drain] surface temperature. ψJB is measured at the ground pin (pin 3) without using any
thermal adhesives. See Section 10.14 for more information.
