Product details

1.25 MHz switching frequency — inductor sizing and ripple

The TPS62040DGQG4: The 1.25 MHz switching frequency allows the use of a physically smaller inductor compared to lower-frequency converters, shrinking the power-stage footprint on a 10-HVSSOP layout.

Adjustable output from 0.7 V to 6 V

Output is adjustable via an external resistor divider from a 0.7 V reference up to the input voltage. The 0.7 V minimum output suits low-voltage core rails for DSPs and FPGAs; the 1.2 A continuous rating covers moderate loads without needing an external pass transistor.
