Series PFM Controlled, Step‐Up DC/DC Converters (Duty Ratio 75%) ◆Duty 75% ■Applications ●Cellular phones, pagers ◆CMOS Low Power Consumption ◆Operating Voltage : 0.9V~10.0V ◆Output Voltage Range : 2.0V~7.0V ●Palmtops ●Cameras, video recorders ●Portable equipment ◆Output Voltage Accuracy : ±2.5% 4 ■General Description ■Features The XC6382 series is a group of PFM controlled step-up DC/DC converters. 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. Operating (start-up) voltage range : 0.9V~10V 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. ■Typical Application Circuit 2 L 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 Performance Characteristic 1 XC6382A301 L=100μH,C=47μF（Tantalum） (TOP VIEW) SOT-23 CIN 3 VOUT SD CL （Tantalum） GND Efficiency:EFFI（％） VIN 100 80 VIN=1.8V 60 0.9V 1.2V 40 1.5V 20 0 0 20 40 60 80 100 Output Current:IOUT（mA） 487 XC6382 Series ■Pin Configuration 5 3 1 5 2 1 2 3 1 SOT-23 (TOP VIEW) 4 4 SOT-25 (TOP VIEW) 2 3 1 SOT-89 (TOP VIEW) 2 SOT-89-5 (TOP VIEW) ■Pin Assignment 4 (XC6382A, XC6382B) PIN NUMBER XC6382A XC6382B PIN NAME FUNCTION SOT-23 SOT-89 SOT-23 SOT-89 1 1 1 1 VSS Ground 3 2 3 2 VOUT Output voltage monitor, IC internal power supply 2 3 – – Lx Switch – – 2 3 EXT External switch transistor drive PIN NAME FUNCTION (XC6382C, XC6382D) PIN NUMBER XC6382C XC6382D SOT-25 SOT-89-5 SOT-25 SOT-89-5 4 5 4 5 VSS Ground VDD Output voltage monitor, IC internal power supply 2 2 2 2 5 4 – – Lx Switch – – 5 4 EXT External switch transistor drive 1 3 1 3 CE Chip enable 3 1 3 1 NC No connection PIN NAME FUNCTION (XC6382E, XC6382F) PIN NUMBER XC6382E 488 XC6382F SOT-25 SOT-89-5 SOT-25 SOT-89-5 4 5 4 5 VSS Ground 2 2 2 2 VDD IC internal power supply 5 4 – – Lx Switch – – 5 4 EXT External switch transistor drive 1 3 1 3 VOUT Output voltage monitor 3 1 3 1 NC No connection 3 XC6382 Series ■Product Classification ●Selection Guide PART TYPE DUTY RATIO PACKAGE SWITCHING RELATED XC6382A 75% SOT-23, SOT-89 Built-in Transistor "Lx" lead XC6382B 75% SOT-23, SOT-89 External Transistor "EXT" lead XC6382C 75% SOT-25, SOT-89-5 Built-in Transistor "Lx" lead Chip Enable(CE) XC6382D 75% SOT-25, SOT-89-5 External Transistor "EXT" lead Chip Enable(CE) XC6382E 75% SOT-25, SOT-89-5 Built-in Transistor "Lx" lead • Independent power supply and set-up voltage Separated "VDD" and "VOUT" leads sensing leads allow designing of PFM controllers.

See Typical Application Circuits, Fig.5. Note: 1. The Schottky diode (SD) must be type MA735, with reverse current (IR) <1.0µA at reverse voltage (VR)=10.0V 2. "Supply current 1" is the supply current while the oscillator is continuously oscillating. In actual operation the oscillator periodically operates which results in less average power consumption. The current actually provided by an external VIN source is represented by "No-Load Input Current (IIN)". When the VDD and VOUT pins are independently used, the voitage range at the VDD pin should be 2.2V to 10V. The IC operates from VDD=0.8V. However, output voltage and oscillator frequency are properly stabilized when VDD=2.2V or higher. * 499 XC6382 XC6382F301MR 4 Series VOUT=3.0V Ta=25°C PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS Output Voltage VOUT L, SD, CL etc. connected 2.925 3.000 3.075 V Maximum Input Voltage VIN V 10 Oscillation Start-up Voltage VST IOUT=1mA Oscillation Hold Voltage VHLD IOUT=1mA Supply Current 1 (Note1) IDD1 VIN=VOUT ✕ 0.95 19.7 39.4 µA Supply Current 2 IDD2 VIN=VOUT+0.5V 2.1 4.2 µA EXT "High" On Resistance REXTH Same as IDD1.
