The Texas Instruments TPS610987DSER is an ultra-low power synchronous boost converter featuring an integrated LDO and VSUB active discharge. Designed for products powered by one or two alkaline, NiCd, or NiMH cells, it offers flexible operation with an input voltage range from 0.7V to 4.5V and selectable output voltages up to 4.3V.
Key electrical characteristics include a typical quiescent current of 300nA in low power mode and a switch current limit of 0.5A. The device supports synchronous rectification and light-load efficiency, achieving up to 93% efficiency at 5mA to 100mA load from a 2V to 3.3V conversion. It has a maximum duty cycle of 90% and operates within a temperature range of -40°C to 125°C.
The TPS610987DSER is housed in a compact 1.5mm x 1.5mm WSON package, making it suitable for space-constrained applications. It features two modes controlled by a MODE pin: Active mode for dual outputs and Low power mode where the LDO/load switch is off, allowing the boost to remain active. The device also supports automatic pass-through.
This converter is ideal for battery-powered devices requiring efficient power management and low quiescent current. Its integrated LDO and load switch functionality simplify design and reduce component count.
