iW1602

Oﬀ-Line Digital Green-Mode

Quasi-Resonant PWM Controller

1 Description

The iW1602 is a high performance AC/DC power supply controller that uses digital control technology to build peak

current mode PWM ﬂyback power supplies. The device operates in quasi-resonant mode to provide high eﬃciency

and includes 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 iW1602 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 iW1602 can achieve both

the highest average active eﬃciency and low no-load power consumption, and have fast dynamic load response

in a compact form factor in typical 5V, 2A, 10W applications. The iW1602 has unique user-conﬁgurable light-load

operation modes to allow optimization of the system cost and performance according to the application requirements

of dynamic load response and no-load power consumption.

2 Features

■ User-conﬁgurable light-load operation modes for

optimized dynamic load response and no-load power

consumption

■ User-conﬁgurable 5-level cable drop compensation

provides design ﬂexibility

■ EZ-EMI^TMdesign enhances manufacturability

■ No-load power consumption < 30mW at 230V_AC

with fast dynamic load response in typical 5V, 2A

10W compact adapter/charger when a secondary-

side controller with Active Voltage Positioning (AVP)

function is used (iW676-30C)

■ Adaptive multi-mode PWM/PFM control improves

eﬃciency

■ Complies with CoC Version 5 Tier 2 and DOE level VI

energy-eﬃciency speciﬁcations with ample margin

■ No-load power consumption < 75mW at 230V_ACalong

with fast dynamic load response in typical 5V, 2A

10W compact adapter/charger applications without a

secondary-side AVP controller

■ Built-in single-point fault protections against output

short-circuit, output over-voltage and output over-

current

■ Dedicated pins for external over-voltage protection,

■ Tight constant-voltage and constant current

with latch function available

regulation across line and load range

■ SmartDefender™ smart hiccup technology helps

to address issues of soft shorts in cables and

connectors by eﬀectively reducing the average output

power at fault conditions without latch

■ Primary-side feedback eliminates optoisolators and

simpliﬁes design

■ Intelligent low power management achieves ultra-low

operating current (~250μA) at no-load

■ Optional on-chip internal over-temperature protection

■ No audible noise over entire operating range

■ Space-saving SOT-23 package

■ Proprietary optimized 89kHz maximum PWM

switching frequency with quasi-resonant operation

achieves best size, eﬃciency and common mode

noise

3 Applications

■ Compact AC/DC adapters/chargers for media tablets

and smart phones

■ AC/DC adapters for consumer electronics
