SLUS772B – MARCH 2008 – REVISED JUNE 2008 4.5-V TO 52-V INPUT CURRENT MODE BOOST CONTROLLER • For Boost, Flyback, SEPIC, LED Drive Apps Device Ratings 2 • Wide Input Operating Voltage: 4.5 V to 52 V Electrical Characteristics 3 • Adjustable Oscillator Frequency Typical Characteristics 5 • Fixed Frequency Current Mode Control • Internal Slope Compensation Terminal Information 10 • Integrated Low-Side Driver Application Information 12 • Programmable Closed Loop Soft Start Additional References 25 • Overcurrent Protection Design Examples 26 • External Synchronization Capable • Reference700-mV (TPS40210), 260-mV (TPS40211) The TPS40210 and TPS40211 are wide-input voltage • Low Current Disable Function (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, • LED Lighting flyback, SEPIC and various LED Driver applications. • Industrial Control Systems The device features include programmable soft start, overcurrent protection with automatic retry and • Battery Powered Systems 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. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
