iW1815 Product Summary
Off-Line Digital Green-Mode PWM Controller
Integrated with Power BJT
1.0 Features
2.0 Description
●● Tight constant voltage and constant current regulation
with PrimAccurate™ primary-side-only feedback
The iW1815 is a high performance AC/DC
power supply control device which uses digital
control technology to build peak-current mode
PWM flyback power supplies. This device
includes an internal power BJT and operates in
quasi-resonant mode to provide high efficiency
along with a number of key built-in protection features while
minimizing the external component count, simplifying EMI
design, and lowering the total bill of material cost. The iW1815
uses Dialog’s advanced PrimAccurate™ primary-side sensing
technology to eliminate the need for secondary feedback
circuitry, while achieving excellent line and load regulation. It
also eliminates the need for loop compensation components
while maintaining stability in all operating conditions. The
pulse-by-pulse waveform analysis allows for fast dynamic load
response for both one-time and repetitive load transients. The
built-in power limit function enables optimized transformer
design for a wide input voltage range.
●● AccuSwitch™ technology with integrated 800V bipolar
junction transistor (BJT)
●● Primary-side sensing technology eliminates optoisolators and simplifies design
●● DIP package for higher power and for single-sided board
●● Adaptively controlled soft start-up enables fast and
smooth start-up for a wide range of output voltage (5V,
12V and above) and capacitve loads up to 6,000μF
●● 64kHz PWM switching frequency
●● No-load power consumption < 30mW at 230VAC with
typical 5V application circuit
●● Fast dynamic load response for both one-time and
repetitive load transients
●● Adaptive multi-mode PWM/PFM control improves
efficiency
●● Quasi-resonant operation for highest overall efficiency
●● EZ-EMI® design easily meets global EMI standards
●● No external compensation components required
●● Built-in single-point fault protections against output short
circuit, output over-voltage, and current-sense-resistor
short-circuit faults
●● Built-in over-temperature protection (OTP)
●● No audible noise over entire operating range
iW1815
Product Summary
Dialog’s innovative proprietary technology ensures that power
supplies built with the iW1815 can achieve highest average

WARNING:
The iW1815 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.

Notes:
1. Maximum practical continuous output power measured at open frame ambient temperture of 50°C and device pins/
package temperatures of ≤ 100°C while minimum bulk capacitor voltage is kept above 90VDC and no special heatsinking
is used (test unit is placed in a non-ventilated environment).
2. The output power capability can vary depending on the power supply system designs and operating conditions.

5.0 Absolute Maximum Ratings
Absolute maximum ratings are the parameter values or ranges which can cause permanent damage if exceeded. For
maximum safe operating conditions, refer to iW1815 datasheet in Section 7.0. (TA = 25°C, unless otherwise noted). Proper
design precautions must be made to ensure that the internal die junction temperature of the iW1815 does not exceed 150°C.
Otherwise permanent damage to the device may occur.

Notes:
1. θJA is measured in a one-cubic-foot natural convection chamber.
2. ψJB [Psi Junction to Board] provides an estimation of the die junction temperature relative to the PCB [Board] surface
temperature. ψJ-BJT [Psi Junction to Collector pin] provides an estimation of the die junction temperature relative
to the collector pin [internal BJT Collector] surface temperature. ψJB is measured at the ground pin (pin 7) without
using any thermal adhesives. See Section 10.14 for more information.
3. These parameters are typical and they are guaranteed by design.
