Introduction
www.DataSheet4U.com
Energy conservation guidelines from the Ministry of Economy,
Trade and Industry’s Agency of Natural Resources and Energy
place considerable emphasis on reducing standby power
consumption of domestic electrical appliances. These guidelines
designate domestic electrical appliances as 'special devices', and
set target years and criteria for achieving these reductions based
on the 'top runner' system. They are characterized by a
considerable degree of severity in that, if targets cannot be
achieved, manufacturers are legally required to publicly
proclaim the fact, and to follow the recommendations of the
Agency of Natural Resources and Energy.
Domestic electrical appliances employing remote controls are
characterized by a standby time which is considerable in
proportion to the duration of daily use. While the absolute value
of the instantaneous power consumption is low, the proportion
of standby power consumption within the total annual power consumption is large, and demands for a
reduction in standby power consumption are therefore becoming increasingly vociferous.
The MR1000 Series products introduced in this paper are standby-compatible partial resonance power
supply IC modules consisting of a multi-chip module (MCM) comprising a control IC and two
MOSFET chips. The ability to develop a standby-compatible partial resonance power supply with a
minimum of external components facilitates a reduction in design time.

MR1000 Series Features
<Implementation of a partial resonance power supply with a simple circuit configuration.
<Use of the burst mode allows a reduction in standby power consumption. With a 100V input
power supply, input power is approximately 100mW at no-load.
<The module contains a start-up circuit to ensure stable start-up and to reduce start-up resistance.
<Full implementation of all protective functions.
These features are described below.
