The TPS40210QDGQRQ1 is a current-mode Boost Controller suitable for topologies that require a grounded source N-channel FET, including boost, flyback, SEPIC and various LED driver applications. This 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.
● Adjustable oscillator frequency
● Fixed-frequency current-mode control
● Internal slope compensation
● Integrated low-side driver
● Programmable closed-loop soft star
● Overcurrent protection
● External synchronization capable
● Low-current disable function
● Green product and no Sb/Br
●Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
