Detailed Product Description
Integrated Circuits IC Texas Instruments (Electronic Components )UCC28220PW UCC28221 UCC28230 UCC28250PW Dual Interleaved PWM controller Integrated circuits IC
Description:
The UCC28220 and UCC28221 are a family of BiCMOS interleaved dual
channel PWM controllers. Peak current mode control is used to
ensure current sharing between the two channels. A precise maximum
duty cycle clamp can be set to any value between 60% and 90% duty
cycle per channel. The UCC28220 has an UVLO turnon threshold of 10 V for use in 12-V supplies while UCC28221 has a turnon threshold
of 13 V for systems needing wider UVLO hysteresis. Both have 8-V
turnoff thresholds. Additional features include a programmable internal slope
compensation with a special circuit which is used to ensure exactly
the same slope is added to each channel and a high-voltage 110-V
internal JFET for easier start-up for the wider hysteresis UCC28221
version. The UCC28220 is available in both 16-pin SOIC and low-profile TSSOP
packages. The UCC28221 also comes in 16-pin SOIC package and a
slightly larger 20-pin TSSOP package to allow for high-voltage pin
spacing to meet UL1950 creepage clearance safety requirements.
