UC3854ADWTR Descrizione

***ical: Power Factor Correction Preregulator 0.3mA 115kHz 16-Pin SOIC T/R

***ser: Power Factor Correction (PFC) ICs Enhanced High Power Factor Preregulator

***i-Key: IC PFC CTR AVERAGE 200KHZ 16SOIC

***ark: Power Factor Controller IC; Frequency:0.2MHz; Supply Voltage Max:20V; Package/Case:16-SOIC; No. of Pins:16; Operating Temperature Range:0°C to +70°C; Leaded Process Compatible:Yes; Peak Reflow Compatible (260 C):Yes ;RoHS Compliant: Yes

***AS INSTRUMENTS INCORPORATED: The UC3854A/B products are pin compatible enhanced versions of the UC3854. Like the UC3854, these products provide all of the functions necessary for active power factor corrected preregulators. The controller achieves near unity power factor by shaping the ac input line current waveform to correspond to the ac input line voltage. To do this the UC3854A/B uses average current mode control. Average current mode control maintains stable, low distortion sinusoidal line current without the need for slope compensation, unlike peak current mode control.

***AS INSTRUM: A 1%, 7.5-V reference, fixed frequency oscillator, PWM, voltage amplifierwith soft-start, line voltage feedforward (VRMS squarer), input supply voltage clamp, and over current comparator round out the lilst of feataures.

***AS INTRUMENTS: Available in the 16-pin N (PDIP), DW (SOIC Wide), and J (CDIP) and 20-pin Q (PLCC) package. See Ordering Information table for availability by temperature range.

***AS INSTRUMENTS INC: The UC3854A/B products improve upon the UC3854 by offering a wide bandwidth, low offset current amplifier, a faster responding and improved accuracy enable comparator, a VREF GOOD comparator, UVLO threshold options (16 V/10 V for offline, 10.5 V/10 V for startup from an auxiliary 12-V regulator), lower startup supply current, and an enhanced multiply/divide circuit. New features like the amplifier output clamps, improved amplifier current sinking capability, and low offset VAC pin reduce the external component count while improving performance. Improved common mode input range of the multiplier output/current amplifier input allow the designer greater flexibility in choosing amethod for current sensing. Unlike its predecessor, RSET controls only oscillator charging current and has no effect on clamping the maximum multiplier output current. This current is now clamped to a maximum of 2 × IAC at all times which simplifies the design process and provides foldback power limiting during brownout and extreme low line conditions.
