Hot-selling and scarce TPS62420QDRCRQ1 2.25-MHz 600-mA/1000-mA DUAL STEP-DOWN CONVERTER QFN10 spot stock

Product Descriptions

The TPS62420 device is a synchronous dual step-down dc-dc converter optimized for battery-powered portableapplications .  It  provides two  independent output voltage  rails  powered  by  1-cell  Li-Ion or 3-cell  NiMH/NiCDbatteries . The device is also suitable to operate from a standard 3.3-V or 5-V voltage rail .

With the EasyScale ™ serial interface the output voltages can be modified during operation . It therefore supportsDynamic Voltage Scaling for low power DSP and processors .

The TPS62420 operates at 2.25-MHz fixed switching frequency and enters Power Save Mode operation at lightload  currents to  maintain  high  efficiency over the  entire  load  current  range .  For  low-noise applications, thedevices can be forced into fixed-frequency PWM mode by pulling the MODE/DATA pin high . In the shutdownmode, the current consumption is reduced to 1.2 μA . The device allows the use of small inductors and capacitorsto achieve a small solution size .

The TPS62420 is available in a 10-pin leadless package (3mm ×3mm QFN).
