QW-R502-032,H PFM CONTROLLED, STEP-UP DC/DC CONVERTERS (VARIABLE DUTY RATIO) DESCRIPTION The UTC UC3383 Series are PFM step-up DC/DC switching converter. The UTC UC3383 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). 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.
