The XC6382 series employs CMOS process and laser trimming technologies so as to attain low power and high accuracy. Max. oscillator frequency is trimmed to 100kHz (accuracy: ±15%) Every built-in switching transistor type enables a step-up circuit to be configured using only three external components ; a coil, a diode, and a capacitor. External transistor versions are available to accommodate high output current applications. 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 V DD pin function (separating power and voltage detect pins). SOT-23, SOT-25 and SOT-89-5 super mini-mold packages. ■Features Operating (start-up) voltage range : 0.9V~10V Output voltage range : 2.0V~7.0V in 0.1V increments Highly accurate : Set-up voltage ±2.5% Maximum oscillator frequency : 100kHz (±15%) Duty ratio : 75%(±5%) Both switching transistor built-in and external types are available. Five-lead packaged units offer either Chip Enable or independent VOUT pin option. Small package : SOT-23, 25 mini-mold (3-pin, 5-pin) SOT-89, 89-5 mini-power mold (3-pin, 5-pin) ■Typical Application Circuit L 2 1 ■Typical Performance Characteristic XC6382A301 L=100μH,C=47μF（Tantalum） (TOP VIEW) SOT-23 VIN CIN 100 Efficiency:EFFI（％） 3 VOUT SD CL （Tantalum） 80 60 0.9V 1.2V 40 20 0 1.5V VIN=1.8V GND 0 20 40 60 80 100 Output Current:IOUT（mA） 487 XC6382 Series ■Pin Configuration 5 3 5 4 4 1 2 1 2 3 1 2 3 1 2 3 SOT-23 (TOP VIEW) SOT-25 (TOP VIEW) SOT-89 (TOP VIEW) SOT-89-5 (TOP VIEW) ■Pin Assignment 4 (XC6382A, XC6382B) PIN NUMBER XC6382A SOT-23 1 3 2 – SOT-89 1 2 3 – XC6382B SOT-23 1 3 – 2 SOT-89 1 2 – 3 VSS VOUT Lx EXT Ground Output voltage monitor, IC internal power supply Switch External switch transistor drive PIN NAME FUNCTION (XC6382C, XC6382D) PIN NUMBER XC6382C SOT-25 4 2 5 – 1 3 SOT-89-5 5 2 4 – 3 1 XC6382D SOT-25 4 2 – 5 1 3 SOT-89-5 5 2 – 4 3 1 VSS VDD Lx EXT CE NC Ground Output voltage monitor, IC internal power supply Switch External switch transistor drive Chip enable No connection PIN NAME FUNCTION (XC6382E, XC6382F) PIN NUMBER XC6382E SOT-25 4 2 5 – 1 3 SOT-89-5 5 2 4 – 3 1 XC6382F SOT-25 4 2 – 5 1 3 SOT-89-5 5 2 – 4 3 1 VSS VDD Lx EXT VOUT NC Ground IC internal power supply Switch External switch transistor drive Output voltage monitor No connection PIN NAME FUNCTION 488 XC6382 Series ■Product Classification GSelection Guide PART TYPE XC6382A DUTY RATIO 75% PACKAGE SOT-23, SOT-89 SOT-23, SOT-89 SOT-25, SOT-89-5 SOT-25, SOT-89-5 SOT-25, SOT-89-5 SOT-25, SOT-89-5 SWITCHING RELATED Built-in Transistor "Lx" lead External Transistor "EXT" lead Built-in Transistor "Lx" lead External Transistor "EXT" lead Built-in Transistor "Lx" lead External Transistor "EXT" lead Chip Enable(CE) ADDITIONAL FUNCTION • Accommodates FEATURES a duty ratio of 75%.
