Features: The Future of Analog IC Technology MP10 3 EasyPowerTM Higher Power Offline Indu ctor-Less Regulator For Low Power Appli cations DESCRIPTION The MP103 provides an easy and low cost ACDC solution for less than 1W applications. It is an of f-line linear regulator that delivers g ood efficiency while generating little EMI noise. It provides an easy solution to step down the AC line voltage to a regulated DC voltage. This offline line ar regulator replaces the conventional switching regulator, not needing a tran sformer or an inductor. Due to its simp licity, it offers an overall low BOM co st. MP103 delivers nearly two times the output power than the MP100 or MP100L by charging its VB capacitor with an ex ternal bipolar transistor. MP103 maximi zes efficiency by minimizing the voltag e drop between VB and VOUT, while only charging VB when VIN is less than appro ximately 32V. The MP103 enables the ove rall system to meet standby power requi rements. MP103 offers rich protections, such as Thermal Shutdow.

MP103 EasyPowerTM
Higher Power
Offline Inductor-Less Regulator
For Low Power Applications
DESCRIPTION
The MP103 provides an easy and low cost
ACDC solution for less than 1W applications. It
is an off-line linear regulator that delivers good
efficiency while generating little EMI noise. It
provides an easy solution to step down the AC
line voltage to a regulated DC voltage. This off-
line linear regulator replaces the conventional
switching regulator, not needing a transformer
or an inductor. Due to its simplicity, it offers an
overall low BOM cost.
MP103 delivers nearly two times the output
power than the MP100 or MP100L by charging
its VB capacitor with an external bipolar
transistor. MP103 maximizes efficiency by
minimizing the voltage drop between VB and
VOUT, while only charging VB when VIN is less
than approximately 32V. The MP103 enables
the overall system to meet standby power
requirements.
MP103 offers rich protections, such as Thermal
Shutdown (TSD), Over Temperature Protection
(OTP), VB Over Voltage Protection (OVP), VB
Short to GND Protection, Over Load Protection
(OLP), Short Circuit Protection (SCP), MP103 is
available in the SOIC8E package.
