ASIC Advantage Puts Spin on Work Horse PWM Controllers With New AAC142/43 and AAC242/43 Sunnyvale, CA, March 8, 2009 – ASIC Advantage, Inc. announces the introduction of the new AAC142/43 and AAC242/4. These four new controllers from ASIC Advantage, Inc., designed as upgrades on the workhorse UC1/2/3842 and UC1/2/3843 family of Current Mode PWM Controllers, available from various sources. The AAC142/43 and AAC242/43 are intended for Offline or DCDC power converter applications, offered as an ongoing expansion in Power Management and other Mixed Signal solutions available from ASIC Advantage, Inc. Features in common with the x842/x843 design include current mode control, pulse-pulse current limiting, undervoltage lockout with hysteresis and an on-board voltage reference. In addition, as with the x842/x843 controllers, the AAC142 and AAC242 are differentiated from the AAC143 and AAC243 by their undervoltage lockout thresholds. The AAC142/242 have turn-on/turn-off thresholds of 16V and 10V respectively, while the AAC143/243 thresholds are 8.4V and 7.6V respectively. The AAC143 and AAC243 are targeted for battery applications, based on their lower undervoltage and hysteresis levels. The lower V-ILimit options of the AAC242/43 of 0.25V, as compared to the 1.0V for the AAC142/43, allow for lower current sense measurements. Other features designed into this family of Current Mode Controllers are intended to enhance their functionality and range of use. The maximum Start-Up current is substantially lower than the x842/x843. Output drive rise and fall times of 50ns for the AAC142/43 and the AAC242/43 compare to 150ns maximum rise and fall times for the x842/x843. Other unique features of the AAC142/43 and AAC242/43 include an integrated soft-start function tied to the clock of the internal oscillator (approximately 330 cycles), leading edge current blanking of 100ns and a more robust, higher current MOS output drive stage capable of driving much higher source and sink currents. The enhancements in drive capability, as well as rise and fall times, enable the AAC142/43 and AAC242/43 to operate up to 1MHz vs. the 500kHz maximum typically ascribed for the x842/843. The AAC142/43 and AAC242/43 are offered in RoHS compliant 8-Pin SOIC, 8-Pin PDIP and 3mm x 3mm 8-Pin DFN packages, with a rated operating temperature range of Extended Industrial (-40°C to +105°C) available. An evaluation board, the AAEV142, AAEV143, AAEV242 or AAEV243, are available for evaluation of the AAC142, AAC143, AAC242 or AAC243 respectively at a price of $99. Pricing on the AAC142/43 and AAC242/43 in 1k quantities is $0.34 in 8-Pin SOIC and 8-Pin P-DIP $0.43 in the 3mm x 3mm/8-Pin DFN, with lower pricing available for high volume production.
