UNISONIC TECHNOLOGIES CO., LTD P2576/HV LINEAR INTEGRATED CIRCUIT 3A STEP-DOWN VOLTAGE SWITCHING REGULATOR  DESCRIPTION As a step-down (buck) switching regulator, the UTC P2576/HV provides drives 3A load. The UTC P2576/HV are simple because it only needs to use a minimum number of external components. Frequency compensation and a fixes-frequency oscillator are in it. UTC P2576/HV can perform with standard inductors, and simplifying the switch mode power supplies’ design. UTC P2576/HV guara.

UNISONIC TECHNOLOGIES CO., LTD P2576/HV LINEAR INTEGRATED CIRCUIT 3A STEP-DOWN VOLTAGE SWITCHING REGULATOR  DESCRIPTION As a step-down (buck) switching regulator, the UTC P2576/HV provides drives 3A load. The UTC P2576/HV are simple because it only needs to use a minimum number of external components. Frequency compensation and a fixes-frequency oscillator are in it. UTC P2576/HV can perform with standard inductors, and simplifying the switch mode power supplies’ design. UTC P2576/HV guarantees output load conditions and ±10% on the oscillator frequency. Its external shutdown is included with 50μA standby current. As well as thermal shutdown for full protection under fault conditions, the output switch has cycle by cycle current limiting.  FEATURES * Output Current 3A * Input Voltage Range of 7V to 40V for P2576 and 7V to 60V for P2576HV * Requires 4 External Components * Very High Efficiency * TTL Shutdown * Low Power Standby Mode * Thermal Shutdown, * Current Limit Protection * Internal Oscillator: 52 kHz Fixed Frequency  ORDERING INFORMATION Ordering Number Lead Free Halogen Free P2576L-xx-TA5-T P2576G-xx-TA5-T P2576L-xx-TB5-T P2576G-xx-TB5-T P2576L-xx-TQ5-R P2576G-xx-TQ5-R P2576L-xx-TQ5-T P2576G-xx-TQ5-T P2576L-xx-S08-R P2576G-xx-S08-R P2576L-xx-SH2-R P2576G-xx-SH2-R P2576HVL-xx-TQ5-R P2576HVG-xx-TQ5-R P2576HVL-xx-TQ5-T P2576HVG-xx-TQ5-T Note: xx: Output Voltage, refer to Marking Information. 1 1 1 Package TO-220-5 TO-220B TO-263-5 TO-263-5 SOP-8 HSOP-8 TO-263-5 TO-263-5 TO-220B TO-220-5 TO-263-5 SOP-8 HSOP-8 Packing Tube Tube Tape Reel Tube Tape Reel Tape Reel Tape Reel Tube P2576XXG-xx-TQ5-T (1) T: Tube, R: Tape Reel (1)Packing Type (2) TA5: TO-220-5, TB5: TO-220B, TQ5: TO-263-5 (2)Package Type S08: SOP-8, SH2: HSOP-8 (3)Output Voltage Code (3) xx: refer to Marking Information (4)Green Package (4) G: Halogen Free and Lead Free, L: Lead Free (5)Supply Voltage Code (5) Blank: 40V, HV: 60V www.unisonic.com.tw Copyright © 2020 Unisonic Technologies Co., Ltd 1 of 9 QW-R101-025.N P2576/HV  MARKING INFORMATION PACKAGE P2576 VOLTAGE CODE TO-220B TO-220-5 TO-263-5 SOP-8 HSOP-8 50:5.0V 33:3.3V 12:12V 15:15V AD:ADJ P2576HV TO-263-5 50:5.0V 33:3.3V 12:12V 15:15V AD:ADJ LINEAR INTEGRATED CIRCUIT MARKING Lot Code Voltage Code UTC P2576□ XXXX□□□□□□ L : Lead Free G: Halogen Free Date Code 12345 8 765 Voltage Code UTC P2576 1 234 Date Code L : Lead Free G: Halogen Free Lot Code Lot Code Voltage Code UTC P2576HV□ XXXX□□□□□□ 12345 L : Lead Free G: Halogen Free Date Code UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 9 QW-R101-025.N P2576/HV  PIN CONFIGURATION LINEAR INTEGRATED CIRCUIT VIN VOUT GND FB ON/OFF TO-220B/TO-220-5/TO-263-5 VIN 1 VOUT 2 FB 3 ON/OFF 4 8 GND 7 GND 6 GND 5 GND VIN 1 VOUT 2 FB 3 ON/OFF 4 GND 8 GND 7 GND 6 GND 5 GND SOP-8 HSOP-8  PIN DESCRIPTIONS For SOP-8/HSOP-8 PIN NO.
