OPTIMIZED FOR VERY LOW STANDBY POWER HICCUP MODE LINE-SIDE OUTPUT POWER LIMITING

Featured Component Description

IPS18 – Ultra-Green Flyback Controller – ASIC Advantage

The new IPS18 Ultra-Green flyback controller is a power saving technology used in Switch

Mode Power Supplies to keep the power consumption to a minimum. It has been optimized

for SMPSs in the 2 - 25 Watts power range that remain connected to the mains wall outlet

with an active load, as well as for applications where an SMPS has to deliver a small

amount of power in "light load" conditions. It monitors the output power from the primary

and no secondary sensing circuitry is required, which also results in power and cost

savings. It incorporates a special circuitry called “HICCUP” that involves a counter and

other digital blocks which prevent delivering a high current to the load when overloaded.

It enters cycle skipping in “no load” or light load” conditions to reduce standby power

to a trickle. The IPS18 can be used in applications where the input voltage ranges from

12 to 400Volts. It also features adjustable frequency from 15 to 500KHz (operating at high

frequency reduces size and cost of magnetic and decoupling components), separate

P & N drive to simplify EMI control, line overvoltage protection and a thermal shutdown.

In most of the applications below 10 Watts it saves costly filtering components such as

X-Cap, Y-Cap. MOV etc...

HICCUP Mode and Protection Against Feedback Loop Failure

The IPS18 flyback controller offers a built-in overload protection called “HICCUP” and

a protection against feedback loop failure with a simple low-cost Zener diode.

(see ASIC Advantage HICCUP MODE FLYBACK CONTROLLERS flyer for details).

IXTY1R4N60P – PolarHV™ Power MOSFET – IXYS

PolarHV™ Power MOSFETs are designed with IXYS unique cell design and process

improvements that dramatically enhance the power handling capability and system

efficiency. These design and process changes provide “best-in-class” on-resistance, gate

charge, thermal resistance and power handling capability. The PolarHV™ line is offered in

500V and 600V versions, with current ratings to as high as 100A. Note that 800V and higher

versions are also in development.

DSS2-60AT2 – Schottky Diode – IXYS

IXYS Schottky diodes feature very low forward voltage drop and switching loss, providing

cost effective output recitification for switch-mode power supply applications. In addition,

the 175°C rated junction temperature and low I

Schottky diodes. The DSS2-60AT2 is offered in the TO-92 to minimize board area and cost.
