IN-PLUG® IPS401 Datasheet - Rev.11 - Universal WHITE LED Controller with 0.5V current FB voltage
IN-PLUG® series: IPS401
High Efficiency, High Power Factor, Universal
High Brightness WHITE LED Controller
INTRODUCTION
– REVISION 11 –
DESCRIPTION
The IPS401 is the world’s first White LED controller
capable of driving one or more strings of up to 120
LEDs in series with high efficiency and power factor
correction. The IPS401 is the forerunner of a series of
Ics which will provide a means of implementing high
efficiency, long life, and reliable lighting systems for
public buildings, industry, homes, transportation
systems and secure installations. It is also the ultimate
solution for RGB backlighting, flat panel display
backlighting and automotive long life lighting and
energy saving requirements. Safety features of the
IPS401 include over voltage and over current
protection.
A host of novel features such as self-oscillating and
continuous mode of operation, PFC capability
together with exceptionally low power dissipation
make the IPS401 a truly breakthrough product which
will establish standards for future “green” lighting
technology.
In addition to the compliance with power factor and
line harmonics regulations, using a PFC offers other
advantages like:
• Reducing the utility bill by making the actual
power drawn from the line almost equal to the
apparent power paid to the utility company
• Allowing more power to be drawn from the wall
outlet or line circuit breaker without exceeding
the limits set by UL or other safety agencies.

- P-channel Ron:
30 Ω typical
- N-channel Ron:
20 Ω typical
A series resistor R3 on pin3 should be added to further reduce EMI and minimize the noise injection which could
result from Miller-capacitance kick-back during transient conditions.
Examples of suitable MOSFETS:
- IXYS PolarHT™ and Polar HV™ MOSFET series: IXTY1R4N60P, IXTY2N60P, IXTY3N60P
- Fairchild MOSFET series: FQPF1N60, FQPF 2N60, FQPF 3N60.
- Infineon COOLMOSTM series: SPD01N60S5, SPD02N60S5, SPD03N60S5.
- Motorola MOSFET series: MTP1N60, MTP2N60, MTP3N60.
- SGS-Thomson MOSFET series: STD1NB60, STD2NB60, STD3NB60. Etc…
Note: Due to the rapid evolution of MOSFET technologies, please check for current models when designing a new
SMPS.

Thermal shutdown:
An internal temperature sensing protection circuit disables the MOSFET gate drive when the temperature exceeds a
typical value of 150°C. This circuit has sufficient hysteresis to prevent relaxation. Normal operations therefore only
resume when the junction temperature has dropped below approximately 120°C.
Shunt bandgap regulator:
The IPS401 internal trimmed bandgap shunt regulator behaves like a 10V zener but also provides the 0.50V
reference for the voltage error amplifier, and the various internal bias current and voltages required by the different
blocks.
During start-up, the current consumption in the regulator is very low, typically 100μA, allowing many possible
schemes to power the IPS401. Once the “zener” value is reached, the MOSFET gate drive is enabled and normal
operation starts. When enabled, the typical chip consumption is 660 μA plus the current necessary to drive the
MOSFET which depends on the MOSFET’s total gate charge and the frequency of operation (linked to L1
inductance value).
The VCC voltage is allowed to drop below the “zener” value during normal operations but the circuit will reset itself
and re-enter start-up mode should the VCC drop below approximately 8 volts.
The shunt regulator is sized to handle up to 50mA, which is especially useful to power the IPS401 with few
components only. Be careful however not to exceed the package rated power dissipation (see table p7).
