TD8211 Datasheet | Techcode

T  echcode®       High Efficiency 1.5MHz, Step Up Regulator General Description  Features     The TD8211 is a fixed switching frequency (1.5MHz typical), z Wide 2.7V to 6V Input Voltage Range  current-mode, step-up regulator with an integrated N-channel z Built‐in 0.2Ω N‐Channel MOSFET  MOSFET. The device allows the usage of small inductors and z Built‐in Soft‐Start  output capacitors for portable devices. The current-mode control z High Efficiency up to 90%  scheme provides fast transient response and good output voltage z <1m A Quiescent Current During Shutdown  accuracy. z Current‐Mode Operation  The TD8211 includes under-voltage lockout, currentlimit,and z Stable with Ceramic Output Capacitors  over-temperature shutdown preventing damage in the event of an z Fast Transient Response  output overload. z Current‐Limit Protection    z Over‐Temperature Protection with Hysteresis  z Available in a SOT‐23‐6A and TDFN2x2‐6 Package  z Lead Free and Green Devices Available  z (Ro HS pliant)  Applications  z Cell Phone and Smart Phone  z PDA, PMP, MP3  z Digital Camera  z Boost Regulators Package Types                       SOT23­6  Figure 1. Package Types of TD8211  October,  20,  2011.                                                        Techcode  Semiconductor  Limited                                                  .techcodesemi.  1  T  echcode®       High Efficiency 1.5MHz, Step Up Regulator Pin Configurations  Pin Description    Figure 2 Pin Configuration of TD8211(Top View)  Pin Number Pin Name Description 1 LX Switch pin. Connect this pin to inductor/diode here.  2 GDN...
