iW1788 targets China tablet and smartphone market, first to be compatible
with MediaTek's new MT6595 octa-core 4G LTE, high power Pump Express Plus

London UK, 10 June 2014 - Dialog Semiconductor plc (FWB:DLG), a provider of
highly integrated power management, AC/DC, solid state lighting and
Bluetooth(R) Smart wireless technology, continues to expand its leadership
momentum in Rapid Charge(TM) mobile device adapter solutions with the
launch of its MediaTek Pump Express(TM) Plus-compatible iW1788 AC/DC
controller. Pump Express Plus is MediaTek's proprietary fast charge
protocol that supports high power chargers with an output of 15W or more
and reduces typical mobile device recharge times by up to 50%.(1) The
iW1788 quickly follows Dialog's recent introduction of its iW1680 Pump
Express-compatible, 5W / 7.5W AC/DC controller in March 2014.

The iW1788 is a single-chip adapter solution that significantly reduces
charge times in USB AC/DC wall chargers for high battery capacity
smartphones and tablets. It uses Dialog's built-in, intelligent rapid
charge digital algorithm to detect commands from smartphones and tablets
designed with MediaTek's Pump Express Plus-compatible MT6595 octa-core LTE
processors. The high power Pump Express Plus protocol enables the phone or
tablet to request voltages as high as 12V from the power adapter to provide
safe and reliable power transfer at 15W or more. This reduces charge times
through more efficient power transfer to the battery.

Built on Dialog's latest PrimAccurate(TM) primary-side controller topology,
the iW1788 Rapid Charge AC/DC controller embeds sophisticated digital
analysis on the primary side of the isolated power supply within the
charger, eliminating the need for intelligence on the secondary side.
PrimAccurate primary-side feedback also eliminates the need for a
secondary-side regulator and opto-isolator for a simple, low component
count solution.

"The biggest shift in smartphone and tablet adapters is the move to fast
charging and we expect broad adoption of fast charge protocols in the
second half of 2014, particularly in the China market," said Mark Tyndall,
Senior VP Corporate Development & Strategy, GM Power Conversion Business
Group at Dialog Semiconductor. "With the introduction of our iW1788 Pump
Express Plus compatible controller, we address the higher power-class
smartphone and tablet market. Combined with the launch of our iW1680 lower
power Pump Express controller in March, this further cements Dialog's
position as the leading supplier of Rapid Charge adapter solutions."

The iW1788 supports power adapters up to 15W, with high active average
efficiency, low no-load power consumption less than 30mW, and a low cost
bill of materials. This provides a high power density solution that
supports fast charging for higher capacity smartphone and tablet batteries
without increasing the size of the adapter. The high efficiency also helps
ensure that specified thermal requirements for the adapter case are not

Communication between the phone and iW1788 is through the VBUS supply line.
The iW1788 digitally manages voltage scaling on the primary side of the
transformer in the AC/DC adapter by analyzing the signal on the VBUS and
scaling its output voltage accordingly from 3.6V to 12V. The iW1788 also
offers a full array of protection features including overvoltage, short
circuit and over-temperature protection.The iW1788 comes in a standard
8-pin SOIC package. Full protection features include built-in output
short-circuit, output overvoltage, output over-current and
current-sense-resistor-short fault protection.
