Product Description

The TPS54140ADGQ is a 42V 1.5A Step-down Converter with an integrated high-side MOSFET and Eco-mode™. 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 116µA. Using the enable pin, shutdown supply current is reduced to 1.3µA. Under-voltage lockout is internally set at 2.5V, but can be increased using the enable pin. The output voltage start-up ramp is controlled by the slow start pin that can also be configured for sequencing/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 external component size to be optimized. Frequency fold back and thermal shutdown protects the part during an overload condition.
200mR High-side MOSFET
High efficiency at light loads with a pulse-skipping Eco-mode™

Adjustable UVLO voltage and hysteresis
116µA Operating quiescent current
1.3µA Shutdown current
100kHz to 2.5MHz Switching frequency
Synchronizes to external clock
Adjustable slow start/sequencing
UV and OV power-good output
0.8V Internal voltage reference
Green product and no Sb/Br
This 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.
