TPS4021x 4.5-V to 52-V Input Current Mode Boost Controller 1 Features 3 Description
• For Boost, Flyback, SEPIC, LED Drive Apps The TPS40210 and TPS40211 are wide-input voltage 1 (4.5 V to 52 V), nonsynchronous boost controllers. • Wide Input Operating Voltage: 4.5 V to 52 V They are suitable for topologies which require a • Adjustable Oscillator Frequency grounded source N-channel FET including boost, • Fixed Frequency Current Mode Control flyback, SEPIC and various LED Driver applications. The device features include programmable soft-start, • Internal Slope Compensation overcurrent protection with automatic retry and • Integrated Low-Side Driver programmable oscillator frequency. Current mode • Programmable Closed-Loop Soft-Start control provides improved transient response and • Overcurrent Protection simplified loop compensation. The main difference between the two parts is the reference voltage to • External Synchronization Capable which the error amplifier regulates the FB pin. • Reference 700 mV (TPS40210), 260 mV (TPS40211)
