1 / 35 page 1/35 XC9110/XC9111 Series PFM Controlled Step-Up DC/DC Converter / Controller ICs ■ GENERAL DESCRIPTION The XC9110/9111 series is a group of PFM controlled step-up DC/DC converter/controller ICs designed to generate low supply voltage by the combination of PFM control and CMOS structure. The series is ideal for applications where a longer battery life is needed such as in portable communication equipment. With a built-in 2.5ΩN-channel driver transistor, the XC9110A/C/E and XC9111A/C/E types provide a step-up operation by using only a coil, a capacitor, and a diode connected externally. The XC9110/9111B, D and F versions can be used with an external transistor for applications requiring larger currents. Output voltage is internally programmable in a range from 1.5V to 7.0V in increments of 100mV (accuracy:±2.5%). Maximum oscillation frequency is set to 100kHz for XC9110/9111 series. (At light loads, it is set to 180kHz for the XC9111 series.) Options include products equipped with a CE pin (C and D versions) that allows the IC to be shut down thereby reducing supply current and with separated VDD/VOUT pins (E and F versions) to separate the power supply block and the output voltage detect block. With the XC9110 series, maximum duty cycle is set to 75% (VDD=3.3V) making it suitable for use with large current operations. The XC9111 series automatically switches duty ratio between 56% & 75% (VDD=3.3V) when it senses changes in load to drop output ripple voltage and can support both large and small currents. The external transistor types (B/D/F types) can be provided for applications, which require larger currents. ■ APPLICATIONS ● Mobile phones ● Various palm top equipment ● Cameras, VCRs ● Various portable equipment ■ FEATURES Operating (Input) Voltage Range : 0.9V ~ 10.0V Output Voltage Range : 1.5V~7.0V (100mV increments, accuracy ±2.5%) Maximum Oscillation Frequency : 100kHz (accuracy ±15%) 180kHz (for the XC9111 series, duty ratio: 56% at light loads) Built-in Switching N-ch Transistor : A/C/E type ON Resistance 2.5Ω (VDD=3.0V) External Transistor Types : B/D/F type Lx Limit Voltage : E type: more than VDD=2.0V : A/C type: more than VOUT=2.0V Low Supply Current : 2.0μA (When operating, VOUT=3V) Small Package : SOT-23 & SOT89 (for XC9111 series), SOT-25, USP-6C ■ TYPICAL APPLICATION CIRCUIT ■TYPICAL PERFORMANCE CHARACTERISTICS ● C type circuit 1 23 54 L CIN CL (Tantalum) (TOP VIEW) SOT-25 GND VOUT CE SD VIN + + 0 20 40 60 80 100 0 5 0 1 00 150 200 250 3 00 Output Current:IOUT(mA) VIN=0.9V 1.2V 1.5V 2.4V 3.0V XC9111E331MR L=100μH(CR54), CL47μF(Tantalum) SD: XB01SB04A2BR ETR0406 004 |
