TI公司的TPS40210和TPS40211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.
