It integrates synchronous rectification and operates at a selectable 350 kHz or 700 kHz switching frequency, which directly determines the inductor value and output capacitor bank — 350 kHz suits larger magnetics for lower ripple, 700 kHz shrinks the filter components at the cost of higher switching losses. ## Switching frequency and output configuration With two transistor-driver outputs and a single-phase topology, the TPS53126RGET drives external N-channel MOSFETs for each rail — the synchronous rectifier pair recovers the body-diode conduction loss, pushing efficiency above what a freewheeling Schottky would deliver in a non-synchronous design. The 350/700 kHz frequency-select pin lets the layout engineer tune the EMI peak away from a sensitive band or match the inductor to a standard value from the 4.7 µH to 22 µH range typical for this class. ## Control features and compliance The Enable pin allows sequencing against a power-good signal from another rail; the Frequency Control pin selects the switching frequency or synchronises to an external clock within the 350/700 kHz window. ROHS3 compliant — no exemptions for lead in solder or PBB/PBDE flame retardants, so the part ships into EU RoHS and China RoHS BOMs without a waiver.","metaTitle":"TI TPS53126RGET Buck Controller, 350/700kHz, 24-VQFN","metaDescription":"Texas Instruments TPS53126RGET active dual-output step-down controller. 4.5-24V input, 350/700kHz switching, 24-VQFN.
