Product details
Overview
AAT3110IGU-5.0-T1 from Skyworks Solutions is a MicroPower™ regulated charge pump IC delivering a stable 5.0 V ±4% output from 2.7–5.0 V input, supporting up to 100 mA load at VIN ≥ 3.0 V. It operates at 750 kHz, consumes only 13 µA quiescent current, and integrates short-circuit and thermal protection. This device serves as a compact, inductorless voltage doubler for portable power rails in space-constrained battery-powered systems.
For engineers reviewing the AAT3110IGU-5.0-T1 datasheet, AAT3110IGU-5.0-T1 pinout, AAT3110IGU-5.0-T1 application, or AAT3110IGU-5.0-T1 equivalent, key selection criteria include regulated 5 V output tolerance, shutdown current <1 µA, SC70JW-8 package compatibility, peak 250 mA pulse capability, and ESD rating of 2 kV - all critical for low-power handheld and imaging subsystems.
Technical Context
The AAT3110IGU-5.0-T1 implements a switched-capacitor voltage-doubling architecture with pulse-skipping regulation to maintain output stability across varying input (2.7–5.0 V) and load (0–100 mA) conditions. Its internal control loop compares a resistor-divided VOUT against a 1.22 V reference to gate switching activity.
Four internal MOSFET switches (S1–S4) operate in non-overlapping phases to charge and transfer energy via an external flying capacitor (CFLY). The device enters idle mode when regulation is met, reducing IQ to ≤13 µA; shutdown mode draws <1 µA. Thermal protection disables operation above ~145°C junction temperature with 10°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±4% - ensures stable logic-level rail for 5 V microcontrollers, displays, and camera flash drivers without external LDO post-regulation. |
| Input Voltage Range | 2.7 V to 5.0 V - supports single-cell Li-ion (3.0–4.2 V), NiMH, and USB 5 V sources with headroom for brownout resilience. |
| Max Output Current | 100 mA at VIN ≥ 3.0 V - sufficient for driving LED backlights (e.g., 3× white LEDs @ 20 mA each) or small display modules. |
| Quiescent Current | 13 µA - enables >1-year battery life in always-on sensor nodes or standby circuits powered by coin cells. |
| Switching Frequency | 750 kHz - allows use of small 1 µF ceramic CFLY and 10 µF COUT, minimizing board area vs. lower-frequency charge pumps. |
| Shutdown Current | <1 µA - essential for ultra-low-power wake-on-event architectures where system sleep dominates duty cycle. |
| Ripple Voltage | ≤30 mVP-P at 100 mA - meets noise requirements for analog front-ends and image sensors without additional filtering. |
Pinout & Package
The AAT3110IGU-5.0-T1 is housed in an 8-pin SC70JW surface-mount package (2.0 mm × 2.1 mm × 0.9 mm), Pb-free and RoHS-compliant, rated for –40°C to +85°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pin 8) | Regulated output node | Bypassed to GND with ≥6.8 µF low-ESR capacitor; supplies 5 V rail to downstream loads. |
| GND (Pins 2, 3, 4) | Ground reference | Three dedicated ground pins minimize impedance and improve thermal dissipation in high-pulse-current operation. |
| SHDN (Pin 5) | Active-low enable control | Logic low (≤0.3 V) disables switching; VIH ≥1.4 V enables operation - compatible with 1.8 V/3.3 V GPIOs. |
| C+ (Pin 6) | Flying capacitor positive terminal | Connects to high side of CFLY during phase 2; requires low-ESR ceramic (e.g., 1 µF X7R). |
| VIN (Pin 7) | Input supply | Bypassed to GND with ≥6.8 µF low-ESR capacitor; accepts 2.7–5.0 V with minimal line regulation error. |
| C− (Pin 1) | Flying capacitor negative terminal | Connects to low side of CFLY during phase 1; forms charge-transfer path with C+ and internal switches. |
Key Features
| Feature | Design Value |
|---|---|
| Voltage doubling with regulation | Maintains 5.0 V ±4% output across full input (2.7–5.0 V) and load (0–100 mA) range using pulse-skipping control. |
| MicroPower operation | 13 µA no-load IQ enables multi-year operation on CR2032 coin cells in IoT edge sensors and wearables. |
| Integrated protection | Short-circuit current limiting and thermal shutdown (145°C trip, 135°C reset) prevent damage during fault conditions. |
| High-frequency switching | 750 kHz oscillator permits compact 1 µF CFLY and 10 µF COUT, reducing total solution size vs. 100–300 kHz alternatives. |
| Low-ESR capacitor optimized | Designed for ceramic capacitors (X7R/X5R); avoids performance degradation from high-ESR tantalum or electrolytic types. |

FAQ
What is the output voltage accuracy of the AAT3110IGU-5.0-T1 over temperature and load?
The AAT3110IGU-5.0-T1 delivers 5.0 V ±4% across –40°C to +85°C ambient and for output currents up to 100 mA at VIN ≥ 3.0 V. Measured data shows normalized output voltage variation of <±0.6% over temperature at 25 mA load, confirming tight regulation without external trimming. This accuracy is maintained by an internal bandgap reference and precision resistor divider network integrated into the AAT3110IGU-5.0-T1 die.
Can the AAT3110IGU-5.0-T1 operate from a 2.7 V input while delivering 100 mA?
No - the AAT3110IGU-5.0-T1 delivers 100 mA only when VIN ≥ 3.0 V. At 2.7 V input, maximum continuous output current is 50 mA per the datasheet's Electrical Characteristics table. Attempting 100 mA at 2.7 V causes output voltage droop below 4.8 V and may trigger thermal protection under sustained load. For full 100 mA capability, ensure minimum 3.0 V supply to the AAT3110IGU-5.0-T1.
What external capacitors are required for stable operation of the AAT3110IGU-5.0-T1?
The AAT3110IGU-5.0-T1 requires three external ceramic capacitors: CIN = 10 µF (bypass at VIN), COUT = 10 µF (bypass at VOUT), and CFLY = 1 µF (flying capacitor between C+ and C−). All must be low-ESR X7R/X5R types (≤100 mΩ). Using smaller values (e.g., 1 µF CIN/COUT for light loads) increases ripple; omitting CIN risks poor start-up regulation. These values are validated in the AAT3110IGU-5.0-T1 typical application circuit.
How does the AAT3110IGU-5.0-T1 respond to a short-circuit event on VOUT?
When VOUT is shorted to GND, the AAT3110IGU-5.0-T1 limits current to ~300 mA and activates thermal protection if junction temperature exceeds ~145°C. The device cycles on/off with 10°C hysteresis (reset at ~135°C), allowing indefinite safe operation without damage. During short-circuit, SHDN remains functional - asserting it forces full shutdown, drawing <1 µA. This behavior is inherent to the AAT3110IGU-5.0-T1's protection architecture.
Is the AAT3110IGU-5.0-T1 pin-compatible with other variants in the AAT3110 family?
Yes - all AAT3110 variants (e.g., AAT3110IGU-4.5-T1, AAT3110ISG-5.0-T1) share identical SC70JW-8 pinout and footprint. The AAT3110IGU-5.0-T1 differs only in factory-trimmed output voltage (5.0 V vs. 4.5 V) and input range (2.7–5.0 V vs. 2.7–4.5 V). No PCB redesign is needed when substituting within the same package; only bill-of-materials and test limits require update for the AAT3110IGU-5.0-T1.
