ICs for Telephone AN1201SM Polarity inverting charge pump DC/DC converter IC ■ Overview AN1201SM is a negative voltage generation IC for bias voltage of transmission power module of cellular phones. This IC is a polarity inverting DC/DC converter to change from positive voltage into negative voltage. ■ Features • High power conversion efficiency: 89% typ. (when output current is 5 mA.) • Low output resistance: 20 Ω typ. • High voltage conversion efficiency: 99.9% • Small (S-MINI) package ■ Applications • Cellular phones ■ Package • SMINI-5DA ■ Block Diagram C2 5 S2 GND 4 OSC S1 S3 1 VIN 2 VOUT S4 3 C1 Publication date: June 2006 SDE00001CEB 1 AN1201SM ■ Pin Descriptions Pin No. 1 2 3 4 5 Symbol VIN VOUT C1 GND C2 Supply voltage pin Inverted output pin Charge pump capacitor's positive polarity side connecting pin Ground pin Charge pump capacitor's negative polarity side connecting pin Description ■ Absolute Maximum Ratings Parameter Supply voltage Supply current Output current Power dissipation *2 *2 Symbol VIN IIN IO PD Topr Tstg *1 Rating 3.3 10 20 48 −30 to +85 −55 to +125 Unit V mA mA mW °C °C Operating ambient temperature Storage temperature Note) 1. Do not apply external currents or voltages to any pins not specifically mentioned. For circuit currents, (+) denotes current flowing into the IC, and (−) denotes current flowing out of the IC. 2. *1: Except for the power dissipation, operating ambient temperature and storage temperature, all ratings are for Ta = 25°C. *2: Ta = 85°C, For the independent IC without a heat sink. ■ Recommended Operating Range Parameter Supply voltage Symbol VIN Range 2.0 to 3.0 Unit V ■ Electrical Characteristics at VIN = 2.5 V, C1 = 1 µF, Ta = 25°C Parameter Consumption current Oscillator frequency Output resistance Voltage conversion efficiency Power efficiency Consumption current in Sleep mode • Design reference data Note) The characteristics listed below are theoretical values based on the IC design and are not guaranteed.

(2) The technical information described in this book is intended only to show the main characteristics and application circuit examples of the products, and no license is granted under any intellectual property right or other right owned by our company or any other company. Therefore, no responsibility is assumed by our company as to the infringement upon any such right owned by any other company which may arise as a result of the use of technical information described in this book. (3) The products described in this book are intended to be used for standard applications or general electronic equipment (such as office equipment, communications equipment, measuring instruments and household appliances). Consult our sales staff in advance for information on the following applications: – Special applications (such as for airplanes, aerospace, automobiles, traffic control equipment, combustion equipment, life support systems and safety devices) in which exceptional quality and reliability are required, or if the failure or malfunction of the products may directly jeopardize life or harm the human body. – Any applications other than the standard applications intended. (4) The products and product specifications described in this book are subject to change without notice for modification and/or improvement. At the final stage of your design, purchasing, or use of the products, therefore, ask for the most up-to-date Product Standards in advance to make sure that the latest specifications satisfy your requirements. (5) When designing your equipment, comply with the range of absolute maximum rating and the guaranteed operating conditions (operating power supply voltage and operating environment etc.). Especially, please be careful not to exceed the range of absolute maximum rating on the transient state, such as power-on, power-off and mode-switching. Otherwise, we will not be liable for any defect which may arise later in your equipment. Even when the products are used within the guaranteed values, take into the consideration of incidence of break down and failure mode, possible to occur to semiconductor products. Measures on the systems such as redundant design, arresting the spread of fire or preventing glitch are recommended in order to prevent physical injury, fire, social damages, for example, by using the products. (6) Comply with the instructions for use in order to prevent breakdown and characteristics change due to external factors (ESD, EOS, thermal stress and mechanical stress) at the time of handling, mounting or at customer's process. When using products for which damp-proof packing is required, satisfy the conditions, such as shelf life and the elapsed time since first opening the packages.
