High Efficiency Step-Down Switching Regulator Controllers

a FEATURES Greater Than 95% Efficiency Current Mode Switching Architecture Provides Superior Load and Line Transient Response Wide Input Voltage Range 3.5 V* to 16 V User Defined Current Limit Short Circuit Protection Shutdown Pin Low Dropout Voltage Low Standby Current 160 ␮A typ Low Cost Available in 8-Lead PDIP or 8-Lead SOIC APPLICATIONS Portable Computers Modems Cellular Telephones Portable Equipment GPS Systems Handheld Instruments GENERAL DESCRIPTION High Efficiency Step-Down Switching Regulator Controllers ADP1147-3.3/ADP1147-5 FUNCTIONAL BLOCK DIAGRAM VIN P-DRIVE GROUND SENSE(+) SENSE(–) ADP1147 2 R Q S SLEEP 1 Q R S S VTH2 VTH1 T OFF-TIME CONTROL VIN V B C 10mV to 150mV VOS 13k⍀ G 1.25V 5pF 100k⍀ REFERENCE SENSE(–) CT ITH SHUTDOWN The ADP1147 is part of a family of High Efficiency Step-Down Switching Regulators. These regulators offer superior load and line transient response, a user defined current limit and an automatic power savings mode. The automatic power savings mode is used to maintain efficiency at lower output currents. The ADP1147 incorporates a constant off-time, current mode switching architecture to drive an external P-channel MOSFET at frequencies up to 250 kHz. Constant off-time switching generates a constant ripple current in the external inductor. This results in a wider input voltage operating range of 3.5 V* to 16 V, and a less complex circuit design. *3.5 volt operation is for the ADP1147-3.3. P-CHANNEL IRF7204 L* 50␮H D1 30BQ040 VI.
