An integrated power supply control
IC with the ability to deliver up to 280% power at peak demands,
has been introduced by Power Integrations,
leader in high-voltage analogue ICs for power conversion.
IC
meets occasional peak power demands
TinySwitch-PK is an innovative
power IC enabling more simple, more flexible designs employing fewer
components than alternative discrete and integrated solutions. Accordingly,
the size, weight and cost of designs are significantly reduced.
It employs an On/Off control method that is highly efficient, easy
to use, and provides an extremely fast transient response; and delivers
peak power on-demand.

A typical application for TinySwitch-PK is a consumer products
having a seldom-used device such as the drawer mechanism in a DVD
player. This requires extra power for short periods, while at all
other times much less power is consumed by the hardware. Conventionally,
all system components such as transformers, output diodes and bulk
storage capacitors, must be specified to cater for that occasional
higher power requirement. By contrast, TinySwitch-PK automatically
enters a special peak mode at times of peak power requirement, in
which it derives up to 280% of the design power level from the same
power components.
TinySwitch-PK integrates a 700V MOSFET with low-voltage control
circuitry on a monolithic IC and offers auto-restart, input under-voltage
and output over-voltage protection, hysteretic thermal shutdown
and, to minimize EMI, frequency jittering. Each family member has
three optional current limit values without the need for additional
pins or external components, so that power supplies may be optimised
for highest efficiency or power output.
