Frequently Asked Questions
How does TPS61202DRCR achieve high efficiency at low input voltages?
TPS61202DRCR uses a synchronous topology with integrated N-channel and P-channel MOSFETs and a 3MHz switching frequency. The synchronous rectifier eliminates the forward voltage loss of a Schottky diode, enabling up to 90% peak efficiency even when the input drops as low as 0.3V — making it ideal for deeply discharged Li-ion or alkaline cells.
Which package does TPS61202DRCR use and what are its dimensions?
TPS61202DRCR comes in a 10-pin WSON (also called VSON) package measuring 3mm × 3mm with a 0.5mm pitch. The thermally-enhanced exposed pad improves heat dissipation. The 'DRC' suffix in the part number denotes this specific package variant from Texas Instruments.
Can TPS61202DRCR replace TPS61023 or similar boost converters?
TPS61202DRCR is pin-compatible and functionally similar to TPS61023DRCR and can often replace XC9141 or MAX1724 series in designs with 0.3–5.5V input requirements. Key differences: TPS61202 operates at 3MHz vs the 1.2MHz of TPS61023, offering smaller external inductors. Verify output voltage setting resistors and inductor saturation current when swapping.
What is the minimum order quantity and lead time for TPS61202DRCR?
The minimum order quantity (MOQ) for TPS61202DRCR is 75 pieces with tiered pricing: $2.69 at 75 pcs down to $1.05 at 10,000+ pcs (USD). FindMyChip carries stock for inquiry — submit an RFQ for volume pricing and confirmed lead-time estimates.
How do I set the output voltage of TPS61202DRCR?
Output voltage is set via a resistor divider from VOUT to the FB pin (0.5V reference). Use the formula: VOUT = 0.5V × (1 + R1/R2). For example, to set 3.3V: R2 = 100kΩ and R1 = 560kΩ. Keep the feedback resistors in the 100kΩ–1MΩ range to minimise quiescent-current impact.
