Dual-rail output — 6 A and 3.5 A
The TPS65276VDAPR integrates two synchronous buck converters with asymmetric current ratings: one channel rated 6 A, the other 3.5 A. This suits a two-rail system where the core draws the higher current and the I/O or auxiliary rail runs lighter. Both outputs are programmable via external feedback dividers, with a minimum output of 0.68 V and a maximum of 1.95 V. The 200 kHz to 1.6 MHz switching frequency range lets the designer choose smaller inductors at higher frequencies or better efficiency at lower ones.
32-HTSSOP with exposed pad
The 0.65 mm pitch is manageable on a two-layer board if the high-current traces are routed on the top layer.
The part is ROHS3 compliant.
