MSC60028

The MSC60028 power factor controller allows the construction of a high performance, low-cost off-line regulator. The feature of MSC60028 are as follows: (1)regulates boost converter output voltage to 390V DC ±5%; (2)maintains typical power factor of 0.99; (3)requires no current transformer; (4)trimmed internal voltage reference; (5)overvoltage sensing eliminates output voltage runaway; (6)may be operated in the continuous current mode to minimise line filltering requirement; (7)uncommitted op-amp for extra flexibility; (8)low power CMOS simplifies line-derived power supply; (9)international voltage operation without selector switches.

The absolute maximum ratings of the MSC60028 are: (1)supply voltage: -0.3V to 12V; (2)digital input voltage: VSS-0.3V to VDD+0.3V; (3)operating temperature: -25 to +85; (4)storage temperature: -55 to +150.

The following is about the electrical characteristics of MSC60028: (1)operating supply voltage: 9V min, 10V typical and 11V max; (2)current consumption: 9mA min, 10mA typical and 12mA max; (3)power dissipation: 90mW min, 100mW typical and 120mW max; (4)power factor: 0.99 typical; (5)bandgap reference decoupling voltage: 1.21V min, 1.28V typical and 1.38V max; (6)peak-peak voltage: 2.23V min, 2.35V typical  and 2.44V max; (7)offset voltage: 2.44V min, 2.52V typical and 2.52V max; (8)output source current: 225mA; (9)input resistance gain: 157k min, 220k typical and 286k max; (10)upper threshold: 7.69V min, 8v typical and 8.24V max; (11)lower threshold: 6.69V min, 7v typical and 7.21V max.
