TPS54240DGQR

Product Summary

The TPS54240DGQR is a 42V, 2.5A, step down regulator with an integrated high side MOSFET. Current modecontrol provides simple external compensation and flexible component selection. A low ripple pulse skip modereduces the no load, regulated output supply current to 138mA. Using the enable pin, shutdown supply current isreduced to 1.3mA, when the enable pin is low.Under voltage lockout is internally set at 2.5V, but can be increased using the enable pin. The output voltagestartup ramp is controlled by the slow start pin that can also be configured for sequencing/tracking. The applications of the TPS54240DGQR include 12-V and 24-V Industrial and Commercial Low Power Systems, GSM, GPRS Modules in Fleet Management, -Meters, and Security Systems.
