UC1852

UC2852

UC3852

High Power-Factor Preregulator

FEATURES

DESCRIPTION

The UC1852 provides a low-cost solution to active power-factor correction (PFC)

for systems that would otherwise draw high peak current pulses from AC power

lines. This circuit implements zero-current switched boost conversion, producing

sinusoidal input currents with a minimum of external components, while keeping

peak current substantially below that of fully-discontinuous converters.

•

Low-Cost Power Factor

Correction

•

Power Factor Greater Than 0.99

Few External Parts Required

Controlled On-Time Boost PWM

Zero-Current Switching

The UC1852 provides controlled switch on-time to regulate the output bulk DC

voltage, an off-time defined by the boost inductor, and a zero-current sensing

circuit to reactivate the switch cycle. Even though switching frequency varies with

both load and instantaneous line voltage, it can be maintained within a reasonable

range to minimize noise generation.

Limited Peak Current

Min and Max Frequency Limits

Starting Current Less Than 1mA

High-Current FET Drive Output

Under-Voltage Lockout

While allowing higher peak switch currents than continuous PFCs such as the

UC1854, this device offers less external circuitry and smaller inductors, yet better

performance and easier line-noise filtering than discontinuous current PFCs with

no sacrifice in complexity or cost. The ability to obtain a power factor in excess of

0.99 makes the UC1852 an optimum choice for low-cost applications in the 50 to

500 watt power range. Protection features of these devices include under-voltage

lockout, output clamping, peak-current limiting, and maximum-frequency

clamping.

The UC1852 family is available in 8-pin plastic and ceramic dual in-line packages,

and in the 8-pin small outline IC package (SOIC). The UC1852 is specified for

operation from -55°C to +125°C, the UC2852 is specified for operation from -40°C

to +85°C, and the UC3852 is specified for operation from 0°C to +70°C.
