AC DC Converter Off Line Electronic Integrated Circuits Quasi Resonant PWM Controller IW1760B-00
The iW1760B is a high performance AC/DC power supply controller which uses digital control
technology to build peak current mode PWM flyback power supplies. The device operates in quasiresonant
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 iW1760B removes the need for 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. 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 iW1760B can achieve both the
highest average active efficiency and less than 50mW no-load power consumption in 20W output power range, and
have fast yet smooth start-up with a wide range of capacitive loads with output voltage up to 12V and above, and are
ideal for network and monitor adapter applications.
● No-load power consumption < 50mW at 230VAC along
with fast dynamic load response and short turn-on
delay in typical 20W and above adapter applications
● Primary-side feedback eliminates opto-isolators and
● 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
● Tight constant-voltage regulation across line and load
● Intelligent low power management achieves ultra-low
operating current (~250μA) at no-load
● Proprietary optimized 79kHz maximum PWM switching
frequency with quasi-resonant operation achieves best
size, efficiency and common mode noise
● User-configurable 5-level cable drop compensation
● EZ-EMI® design enhances manufacturability
● Power adapters for network devices and monitors
● Universal input AC/DC adapters (15W - 45W)
● Adaptive multi-mode PWM/PFM control improves
● Built-in single-point fault protections against output
short-circuit, output over-voltage and output overcurrent
● Dedicated pins for external over-temperature
protection and over-voltage protection, with latch
● Tight constant current control enables output current
limit and over-load protection
● SmartDefender™ smart hiccup technology
helps address issues of soft shorts in cables and
connectors by effectively reducing the average output
power at fault conditions without latch
● On-chip internal over-temperature protection
● No audible noise over entire operating rang
