Product details
Overview
AAT1162IRN-0.6-T1 from Skyworks is a high-efficiency 800 kHz step-down DC/DC switching regulator IC with 4.0–13.2 V input range, 1.5 A output current capability, and fixed 0.6 V output voltage. It integrates internal power MOSFETs and operates in PWM/light-load mode to maintain efficiency across load conditions, targeting mid-power industrial systems powered by regulated 12 V rails.
For engineers reviewing the AAT1162IRN-0.6-T1 datasheet, AAT1162IRN-0.6-T1 pinout, AAT1162IRN-0.6-T1 application, or AAT1162IRN-0.6-T1 equivalent, key selection criteria include its fixed 0.6 V output, TDFN34-16 thermal performance, shutdown current <1 µA, and compatibility with compact 12 V-powered embedded subsystems requiring stable low-voltage bias rails.
Technical Context
The AAT1162IRN-0.6-T1 implements synchronous buck topology with integrated high-side and low-side MOSFETs, enabling 1.5 A continuous output without external power switches. Its 800 kHz fixed-frequency PWM control ensures predictable EMI behavior and supports ceramic output capacitors as small as 10 µF.
Light-load operation transitions automatically to pulse-frequency modulation (PFM) mode, reducing quiescent current to 25 µA typical while maintaining regulation. The device includes internal soft-start (1.2 ms), over-temperature protection, and undervoltage lockout (UVLO) with 3.6 V turn-on threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.0 V to 13.2 V - supports dual-cell Li-ion (8.4 V max) and regulated 12 V industrial supplies. |
| Output Voltage | Fixed 0.6 V - designed for point-of-load regulation of core logic or analog circuitry requiring ultra-low voltage rails. |
| Max Output Current | 1.5 A - sufficient for powering FPGA I/O banks, microcontroller cores, or sensor signal chains. |
| Switching Frequency | 800 kHz - enables use of ≤2.2 µH inductors and 10–22 µF ceramic output capacitors, minimizing board area. |
| Shutdown Current | <1 µA - isolates load from VIN during system sleep, critical for battery-backed or energy-harvesting designs. |
| Operating Temp | −40°C to +85°C - qualified for industrial ambient environments without derating. |
Pinout & Package
Package: 16-pin TDFN34 (3.0 mm × 3.0 mm, 0.5 mm pitch), thermally enhanced with exposed thermal pad (EP) tied to GND for PCB-level heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input Power Supply | Accepts 4.0–13.2 V; requires local 10 µF ceramic decoupling adjacent to pin. |
| VOUT | Regulated Output | Delivers fixed 0.6 V; connects directly to load and output capacitor bank. |
| GND | Power Ground | Common return for power stage and control circuitry; must be low-impedance plane under EP. |
| EN | Enable Input | Active-high logic control; pulls low to enter shutdown (<1 µA IQ). |
| FB | Feedback Input | Internally tied to 0.6 V reference; not accessible - output is fixed, no external resistor divider. |
| SS | Soft-Start Capacitor | Connects to external capacitor (typically 1 nF) to set 1.2 ms startup ramp and limit inrush current. |
| EP | Thermal Pad | Exposed copper pad on bottom; must be soldered to ≥4 cm² GND copper area for thermal management. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous Buck Architecture | Integrated high-side and low-side MOSFETs eliminate need for external diode or second switch, reducing BOM count and conduction losses. |
| PWM/PFM Hybrid Control | Automatic transition between fixed-frequency PWM (full load) and PFM (light load) maintains >85% efficiency down to 1 mA output current. |
| Thermally Optimized Package | TDFN34-16 with exposed pad achieves θJA = 45°C/W on 4-layer PCB, enabling 1.5 A operation without heatsink at +70°C ambient. |
| Internal Soft-Start | 1.2 ms controlled ramp prevents input voltage sag and output overshoot during power-up, eliminating need for external timing components. |
| UVLO with Hysteresis | 3.6 V turn-on / 3.3 V turn-off threshold prevents oscillation near brownout conditions in noisy 12 V supply rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62130ARGTR | 3–17 V input, adjustable output (0.6–6 V), 3 A rating, 2.5 MHz switching frequency. | Requires external feedback resistors; higher frequency allows smaller magnetics but increases EMI filtering complexity. | Preferred when adjustable output or higher current headroom is needed; not pin-compatible with AAT1162IRN-0.6-T1. |
| MP2315GJ-Z | 4.5–24 V input, fixed 0.6 V output, 2 A rating, 500 kHz switching frequency, QFN-10 package. | Lower switching frequency demands larger inductor (4.7 µH vs. 2.2 µH); smaller package lacks thermal pad, limiting sustained 1.5 A operation. | Offers higher current rating in smaller footprint but reduced thermal margin; suitable only with aggressive PCB copper pour. |
Compared with TPS62130ARGTR and MP2315GJ-Z, the AAT1162IRN-0.6-T1 delivers optimal thermal performance in space-constrained industrial modules via its TDFN34-16 EP package, while its fixed 0.6 V output and integrated soft-start simplify layout for cost-sensitive 12 V–powered edge devices.

FAQ
Is AAT1162IRN-0.6-T1 still in active production?
No, the AAT1162IRN-0.6-T1 is officially discontinued by Skyworks. However, Aetrix Electronics maintains verified legacy inventory with full traceability and provides lifecycle coordination support to help customers manage last-time buys and transition planning for the AAT1162IRN-0.6-T1.
What is the purpose of the SS pin on the AAT1162IRN-0.6-T1?
The SS (Soft-Start) pin on the AAT1162IRN-0.6-T1 connects to an external capacitor that sets the output voltage ramp time during startup. A typical 1 nF capacitor yields a 1.2 ms soft-start period, preventing input surge current and output overshoot-critical for reliable power sequencing in the AAT1162IRN-0.6-T1's target applications.
Can AAT1162IRN-0.6-T1 be used with input voltages below 4.0 V?
No. The AAT1162IRN-0.6-T1 has a minimum input voltage specification of 4.0 V due to internal UVLO and gate drive limitations. Operation below this threshold will cause the device to shut down or fail to regulate. For sub-4 V inputs, alternative regulators such as the AAT1161 series should be evaluated instead of the AAT1162IRN-0.6-T1.
Does AAT1162IRN-0.6-T1 require an external feedback resistor network?
No. The AAT1162IRN-0.6-T1 features a factory-trimmed internal feedback network that fixes the output voltage at 0.6 V. The FB pin is not brought out externally and must remain unconnected. This eliminates resistor tolerance errors and simplifies design versus adjustable alternatives like the AAT1162IRN-ADJ variant.
How is thermal performance managed on the AAT1162IRN-0.6-T1?
The AAT1162IRN-0.6-T1 uses a TDFN34-16 package with an exposed thermal pad (EP) that must be soldered to a dedicated GND copper area of ≥4 cm². Proper thermal land design reduces junction-to-ambient thermal resistance to 45°C/W, allowing full 1.5 A output at +70°C ambient-key to sustained performance in the AAT1162IRN-0.6-T1's industrial deployments.
