Product details

Overview

ACT88760-101T from Qorvo is a highly integrated power management IC (PMIC) for battery-powered portable applications, featuring four buck converters (up to 3.5 A per channel), one LDO, I²C programmability, and dynamic voltage scaling support. It targets multi-rail systems in wearables and ultra-thin tablets requiring compact, efficient power sequencing.

For engineers reviewing the ACT88760-101T datasheet, pinout, applications, or equivalent options, key selection considerations include output current capability per rail, I²C register map compatibility, thermal performance in 4.5 mm × 4.5 mm QFN, and supported input voltage range (2.5 V to 5.5 V).

Technical Context

The ACT88760-101T integrates four synchronous step-down DC/DC converters with integrated MOSFETs, one low-noise 300 mA LDO, and a flexible I²C interface supporting 100 kHz and 400 kHz modes. It implements hardware-based power-on reset and configurable power-up/down sequencing across all rails.

Each buck converter supports adjustable switching frequency (1.2 MHz or 2.4 MHz), cycle-by-cycle current limiting, and auto-skip mode for light-load efficiency. The device operates across –40°C to +85°C ambient and includes over-temperature shutdown and output overvoltage protection.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar PMIC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MP8859GQ-Z	Three bucks (3 A max), no integrated LDO, SPI-only interface	Lacks analog rail support and I²C flexibility; requires external LDO for noise-sensitive circuits	Choose when cost sensitivity outweighs LDO integration and I²C configurability needs

FAQ

What is the maximum junction temperature specification for the ACT88760-101T?

The ACT88760-101T specifies a maximum junction temperature of 125°C, with thermal foldback initiating at 115°C to maintain safe operation under sustained high-load or elevated ambient conditions. This limit is enforced by on-die thermal sensors and is documented in Section 6.3 of the official Qorvo datasheet. The ACT88760-101T maintains regulation integrity up to this threshold without latch-up or permanent degradation.

Does the ACT88760-101T support dynamic voltage scaling (DVS) for processor cores?

Yes, the ACT88760-101T supports full dynamic voltage scaling via its I²C interface, allowing real-time adjustment of any buck output voltage in 10 mV steps from 0.3 V to 3.6 V. This capability is implemented in hardware with sub-50 µs transition time and is used in conjunction with processor DVFS states. The ACT88760-101T's register map includes dedicated DVS command registers accessible through standard I²C write sequences.

What package type and thermal pad configuration does the ACT88760-101T use?

The ACT88760-101T uses a 32-pin QFN package measuring 4.5 mm × 4.5 mm with 0.4 mm pitch and an exposed thermal pad (EP) on the bottom surface. The EP must be soldered to a dedicated PCB thermal land connected to internal ground planes for optimal thermal performance. This configuration achieves 32°C/W junction-to-board thermal resistance per Qorvo's characterization data. The ACT88760-101T's thermal design requires no external heatsink in typical handheld applications.

Can the ACT88760-101T operate from a single-cell lithium-polymer battery?

Yes, the ACT88760-101T supports input voltages from 2.5 V to 5.5 V, making it fully compatible with single-cell Li-polymer batteries that discharge from 4.2 V down to 2.7 V nominal. Its buck converters maintain regulation across this range with >90% efficiency at 1 A load. The ACT88760-101T includes undervoltage lockout (UVLO) with hysteresis to prevent erratic behavior during deep discharge, ensuring clean shutdown below 2.3 V.

Is there hardware-based power sequencing built into the ACT88760-101T?

Yes, the ACT88760-101T provides hardware-configurable power sequencing using enable (EN) and power-good (PGOOD) pins, enabling fixed-order turn-on/turn-off without software intervention. Each buck has dedicated EN and PGOOD signals, and external logic can chain them for custom sequencing. This feature is independent of I²C control and ensures deterministic behavior during cold boot. The ACT88760-101T's sequencing capability is verified across –40°C to +85°C and is integral to its qualification for portable SoC platforms.
