DESCRIPTION

· TDA 4862 is a Power-Factor Controller (PFC) IC designed for high power factor and active harmonic filtering.

· Available in PG-DIP-8-1 and PG-DSO-8-1 packages.

FEATURES

· Ensures sinusoidal line-current consumption with a power factor close to 1.

· Controls boost converters as active harmonics filters.

· Features internal start-up with low current consumption.

· Includes a zero current detector for discontinuous operation mode.

· High current totem pole gate driver.

· Internal reference trimmed to ±1.4%.

· Undervoltage lock-out with hysteresis.

· Very low start-up current consumption.

· Pin compatible with world standards.

· Fast overvoltage regulator.

· Current sense input with internal low pass filter.

APPLICATIONS

· Suitable for applications requiring high power factor and active harmonic filtering.
