L3383

UNISONIC TECHNOLOGIES CO., LTD L3383 PFM CONTROLLED, STEP-UP DC/DC CONVERTERS (VARIABLE DUTY RATIO) DESCRIPTION The UTC L3383 Series are PFM step-up DC/DC switching converter. The UTC L3383 can support both large and small currents. It automatically switches duty ratio (45%/75%) when it senses changes in load. Both built-in and external transistor types include 5-pin and 3-pin packages, which are provided with either a CE (chip enable) function that reduces power consumption during shut-down mode, or a VDD pin function (separated power and voltage detect pins). 1 1 CMOS IC 3 2 5 4 SOT-25 SOT-89 FEATURES * Output voltage range: 2.0V~7.0V in 0.1V increments * Operating (start-up) voltage range: 0.9V~10V * Highly accurate: Set-up voltage ±2.5% * Maximum oscillator frequency (Max Fosc1): 180kHz (±15%) * Variable Duty Ratio: 45%/75% (±5%) * Both switching transistor built-in and external types are available * 5-lead package offer Chip Enable or independent VOUT pin option. *Pb-free plating product number: L3383L ORDERING INFORMATION Order Number Normal Lead Free Plating L3383-xx-AB3-R L3383L-xx-AB3-R L3383-xx-AF5-R L3383L-xx-AF5-R Package SOT-89 SOT-25 1 G E Pin Assignment 23 4 5 O I ON G I Packing Tape Reel Tape Reel Note: Pin Assignment: I:VIN O:VOUT G:GND N: No Connection E: Chip Enable xx: Output Voltage, refer to Marking Information.
