- Dual-output single-chip solution reduces BOM count and simplifies power tree design
Applications
TPS62770 is targeted at ultra-low-power wearables, medical patches, and IoT sensor nodes where battery longevity is critical and board space is at a premium. Its 360nA buck quiescent current keeps standby drain negligible for coin-cell and thin-film battery powered designs. The integrated 15V boost output simultaneously powers displays, piezo drivers, or RF front-ends from the same IC, simplifying the overall power architecture.

Frequently Asked Questions
How does TPS62770's 360nA quiescent current compare to typical LDO-based solutions for coin-cell powered sensors?
At 360nA quiescent current, the TPS62770 buck converter draws far less standby current than most LDOs, which typically idle at 1µA to 50µA. This difference can extend a CR2032 coin cell's life by months in always-on sensor applications, since the buck's switching efficiency also outperforms LDO dropout losses at low duty cycles, effectively delivering more usable energy per milliamp-hour of cell capacity.
What output voltage range can the TPS62770 boost converter supply for display or piezo applications?
The TPS62770 boost stage can regulate an output up to 15V from a low-voltage battery input, covering the drive requirements for OLED displays, electroluminescent panels, and piezoelectric transducers. This 15V ceiling is sufficient for most small-panel display bias rails and piezo haptic drivers used in wearables and medical devices, eliminating the need for a separate high-voltage boost IC.
Is TPS62770 suitable for dual-rail designs in Bluetooth Low Energy wearable devices?
Yes, the TPS62770 is well matched to BLE wearables that need both a regulated 1.8V or 3.3V core rail from the buck stage and a higher voltage up to 15V for a display or sensor bias from the boost stage. With 360nA total quiescent current from the buck and compact WCSP packaging, it keeps the power budget tight for CR2032 or LiPo cells while serving both rails with a single-chip solution.
How small is the TPS62770 WCSP package and how does it fit into ultra-compact PCB layouts?
The TPS62770 ships in a WCSP (wafer chip-scale package) that occupies approximately 1.5mm x 1.5mm of board area with a sub-millimeter pitch, making it one of the smallest dual-function PMICs available. This footprint allows designers to fit the entire power section, including the IC and a few passive components, within a few square millimeters — critical for smartwatches, hearing aids, and disposable medical patches with strict size constraints.
