TPS54240DRCR

Импульсный понижающий DC-DC стабилизатор, регулируемый, 3.5В-42В (Vin), 800мВ-39В, 2.5А, SON-10.

The TPS54240DRCR is a Step-down Regulator with an integrated high-side MOSFET. Current-mode control provides simple external compensation and flexible component selection. A low-ripple, pulse skip mode reduces the no load, regulated output supply current to 138µA. Using the enable pin, shutdown supply current is reduced to 1.3µA, when the enable pin is low. Undervoltage lockout is internally set at 2.5V, but it can be increased using the enable pin. The output voltage startup ramp is controlled by the slow-start pin that can also be configured for sequencing and tracking. An open-drain power good signal indicates the output is within 94 to 107% of its nominal voltage. A wide switching frequency range allows efficiency and optimization of external component size. Frequency foldback and thermal shutdown protects the part during an overload condition.
