JIANGSU CHANGJING ELECTRONICS TECHNOLOGY CO., LTD Small Package PFM Control Step-Up DC/DC Converter CJ9117 Series  INTRODUCTION The CJ9117 Series is a CMOS PFM-control  FEATURES  Low voltage operation: Startup at 0.9 V step-up switching DC/DC converter. The PFM controller allows the duty ratio to min. (IOUT = 1 mA) guaranteed be  automatically switched according to the load Duty ratio: 66/78%, built in auto switching type PFM controller (light load: 66%, high output current: 78%),  External parts: Coil, capacitor, diode enabling products with a low ripple over a wide  Output voltage: Settable to between 1.8V range, high efficiency, and high output current. to 6.0 V in 0.1 V steps With the CJ9117 Series, a step-up switching  Accuracy of ±2% DC/DC converter can be configured by using  High efficiency：±85%（typ.） an external coil, capacitor, and diode. The  Standard function (product type A) built-in MOSFET is turned off by a protection  Shutdown function (product type C,D) circuit when the voltage at the LX pin exceeds  External transistor type available the limit to prevent it from being damaged. This (product type B、D) feature, along with the mini package and low current consumption, makes the CJ9117 Series ideal for applications such as the power supply unit of portable equipment.  APPLICATIONS  Digital cameras  Cameras, video equipment,  Electronic notebooks and PDAs  Communications equipment  Portable CD/MD players  Power supply for microcomputers  BLOCK DIAGRAM „ DEVICE INFORMATION: CJ9117 ①②③④ DESIGNATOR SYMBOL A B ① C D ②③ ④ www.jscj-elec.com 1 Integer T3/T5 R/H L DESCRIPTION Standard LX Standard EXT With shutdown, LX With shutdown, EXT Output Voltage（1.8～6.0） e.g.：3.0V=②:3; ③:0 Package：SOT-23-3/5L Package：SOT-89-3/5L Package：TO-92 Rev. - 1.0 Pin$onfiguration CJ9117A Series（SOT-23-3L PKG） Table 1 SOT-23-3L Top view PIN NO.
