TPS60500 Step-Down Charge Pump Converter

Specifications

Product Overview

The TPS60500 is a Texas Instruments step-down charge pump converter for Power_Management designs. The adjustable TPS60500 version provides a 0.8 V to 3.3 V output range, while the related TPS60501, TPS60502, and TPS60503 variants provide fixed 3.3 V, 1.8 V, and 1.5 V outputs respectively.

The device operates from a recommended 1.8 V to 6.5 V VIN range and supports up to 250 mA at OUT under recommended operating conditions. Electrical characteristics include 0.8 V feedback voltage for TPS60500, 30 mVpp output ripple at 150 mA with VOUT = 1.5 V, 40 µA typical quiescent current at no load, and 0.05 µA typical shutdown supply current when VEN = VIN.

Assembly uses a 10-pin VSSOP (DGS) package with 3.05 mm x 4.98 mm nominal body size. Recommended external capacitors include a 2.2 µF input capacitor, 1 µF flying capacitors, and either 4.7 µF or 22 µF output capacitance depending on output current range. The EN pin uses active-low enable logic, and PG is an open-drain power-good output.

Procurement Notes

When requesting a quote for TPS60500, 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.
