Product Overview
The TPS62065 from Texas Instruments is a Power_Management power IC for step-down conversion. The device family is specified for 2 A output current capability and operates from a recommended 2.9 to 6 V input range. Its switching frequency is 3 MHz typical, with 2.6 MHz minimum and 3.4 MHz maximum over 2.9 V <= VIN <= 6 V.
Output regulation is based on a 600 mV typical reference, with +/-1.5% output voltage accuracy in PWM mode and an adjustable output range from 0.8 V to VIN. The MODE pin selects fixed-frequency PWM when high, or enables power-save automatic PFM/PWM transition when low. Typical quiescent current is 18 uA in PFM mode with no switching, and shutdown current is 0.1 uA typical.
The package is WSON (DSG), 8-pin, 2.00 mm x 2.00 mm x 0.75 mm nominal. Recommended external component ranges include 0.7 uH to 1.6 uH effective inductance and 4.5 uF to 22 uF effective output capacitance. Thermal data for the package includes 65.3°C/W junction-to-ambient resistance and 12.8°C/W junction-to-case bottom resistance.

Procurement Notes
When requesting a quote for TPS62065, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For power IC and power device sourcing, voltage rating, current rating, power dissipation, package thermal performance, protection features, qualification grade and application conditions should be reviewed before approval.
FAQ
What input voltage range does TPS62065 support?
TPS62065 is specified with a recommended input voltage range of 2.9 to 6 V. The absolute maximum rating for AVIN and PVIN is -0.3 V to 7 V over the operating free-air temperature range.
What output current and switching frequency are specified?
The device family output current capability is 2 A. Switching frequency is specified as 3 MHz typical, with a 2.6 MHz minimum and 3.4 MHz maximum over 2.9 V <= VIN <= 6 V.
