2011-05-29 19:07:23来源: 互联网

TI公司的TPS40210TPS40211是宽输入电压(4.5V-52V)电流模式异步升压控制器,具有可编程软起动特性,带自动重起的过流保护和可编程的振荡频率,广泛应用于LED照明,工业控制系统以及以电池为能源的系统。本文介绍了TPS40210和TPS40211的主要特性,功能方框图以及几种设计案例和相应的所用材料清单(BOM)。

                  TPS40210, TPS40211 4.5-V TO 52-V INPUT CURRENT MODE BOOST
                  ONTROLLER

                  The TPS40210 and TPS40211 are wide-input voltage (4.5 V to 52
                  V), non-synchronous boost controllers. They are suitable for
                  topologies which require a grounded source N-channel FET
                  including boost, flyback, SEPIC and various LED Driver
                  applications. The device features include programmable soft
                  start, overcurrent protection with automatic retry and
                  programmable oscillator frequency. Current mode control
                  provides improved transient response and simplified loop
                  compensation. The main difference between the two parts is the
                  reference voltage to which the error amplifier regulates the
                  FB pin.

                  主要特性:
                  Suitable for Boost, Flyback, SEPIC, and LED Driver Topologies
                  Wide Input Operating Voltage: 4.5 V to 52 V
                  Adjustable Oscillator Frequency
                  Fixed Frequency Current Mode Control
                  Internal Slope Compensation
                  Integrated Low-Side Driver
                  Programmable Closed Loop Soft Start
                  Overcurrent Protection
                  700-mV Reference (TPS40210)
                  263-mV Reference (TPS40211)
                  Low Current Disable Function

                  应用:
                  LED Lighting
                  Industrial Control Systems
                  Battery Powered Systems
