IPS101I-D Datasheet | ASIC Advantage

DESCRIPTION The IN-PLUG® IPS101 is a special line-side switching controller which provides simple yet high performance active power factor correction. The IPS101 was optimized for electronic ballast pact SMPSs up to 300W that requires a minimum board area, reduced ponent count and high efficiency. The PFC forces the SMPS to draw a current proportional to the instant AC line voltage in order to charge a storage capacitor thus resulting in excellent power factor and low line harmonics generation. The output of the PFC is a regulated voltage which slightly exceeds the peak line voltage and is generally too high to be used as is. This is why a PFC is usually followed by a DC/DC converter, providing one or more isolated output(s) at the required voltage(s). AAI offers the following solutions for the DC/DC converter: - Flyback converters (see IPS10 series) - Push-pull converters (see IPS201 controller) Other ICs and discrete solutions can be used as well. More and more countries already impose PFC above 75W or soon will enforce this obligation. In addition to the pliance 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 pany - Allowing to draw more power from the wall outlet or line circuit breaker without exceeding the limits set by UL or other safety agencies. FEATURES - Simple and easy to use. - High efficiency over 96% (in optimized designs) - Minimum external ponent count for lowest cost. - 3-input current-mode multiplier ensures outstanding performance at any line voltage and any load. - Under voltage protection. - Voltage error amplifier with provision for loop stability pensation. - Cycle to cycle current limiting. - Thermal shut-down. - Capable of driving a broad range of power MOSFETs. - Self oscillating at frequencies up to 300KHz APPLICATIONS - SMPS. - Electronic ballast.
