Tps54140adgqr msop-10 switching regulator IC is original and in stock
explain
Tps54140a device is a 42V, 1.5A, step-down regulator with integrated high side MOSFET. It adopts current mode control, which can realize simple external compensation and flexible component selection. Its low ripple pulse jump mode can reduce the no-load regulated output power supply current to 116 μ A。 By using the enable pin, the shutdown power supply current can be reduced to 1.3 μ A。
The undervoltage locking voltage is internally set to 2.5V, but can be increased by the enable pin. The output voltage start ramp is controlled by the slow start pin, which can also be configured to control sorting / tracking. An open drain power supply normal signal indicates that the output is within 94% to 107% of its nominal voltage.
The wide switching frequency range allows optimization of efficiency and external component size. Frequency turn back and thermal shutdown functions protect components in case of overload.
