The TPS60300DGS is a dual-output charge pump that generates a ratiometric output from the input voltage and a fixed 3.3 V rail, both from a single 0.9 V to 1.8 V input — think a single alkaline or Li-ion cell powering a mixed-voltage sensor node. One output delivers 40 mA, the other 20 mA, with the 700 kHz switching frequency keeping the external flying capacitors small enough for the 10-VSSOP footprint.
No. The TPS60300DGS is a charge pump (step-up, dual output, 40mA/20mA), while the TPS65261RHBT is a 3-output buck converter rated for 3 A per channel. They share neither topology nor pinout — a board redesign is required to swap between them.
Texas Instruments certifies the TPS60300DGS as ROHS3 compliant. Full material declaration and REACH SVHC data are available in the TI product page and the RoHS certificate of compliance.
