Product details
Overview
AAT1210IRN-0.6-T1 from Skyworks Solutions is a high-power DC/DC boost converter IC with 2.7–5.5V input range, 0.5V above VIN to 18V programmable output, integrated N- and P-channel MOSFETs, hysteretic current-mode control, and true load disconnect enabling <1μA shutdown quiescent current. It delivers up to 900mA at 5V output and supports dynamic voltage programming via S2Cwire™ or dual-voltage toggle using the SEL pin - ideal for portable media players requiring efficient, compact, battery-life-optimized voltage boosting.
For engineers reviewing the AAT1210IRN-0.6-T1 datasheet, AAT1210IRN-0.6-T1 pinout, AAT1210IRN-0.6-T1 application, or AAT1210IRN-0.6-T1 equivalent, this page provides verified technical context on its hysteretic control architecture, TDFN34-16 thermal performance, FB1/FB2 dual-reference feedback system, and real-world output capability curves across 5–18V at varying input voltages and loads.
Technical Context
The AAT1210IRN-0.6-T1 implements a hysteretic current-mode control loop with no external compensation required, achieving stable operation across wide input/output ranges and excellent transient response. Its dual feedback references (FB1 = 1.2V, FB2 = 0.6V) enable precise output voltage selection via SEL logic or 16-level S2Cwire™ programming.
It integrates low-RDS(ON) N-channel (60mΩ typ.) and P-channel (180mΩ typ.) MOSFETs, supports up to 2MHz switching, and features cycle-by-cycle current limiting (3.0A min.), over-temperature shutdown (140°C), and soft-start (2.5ms typ.) - all in a thermally enhanced 3×4mm TDFN package rated for –40°C to +85°C.

Pinout & Package
Package: Pb-free, thermally enhanced 16-pin TDFN34-16 (3mm × 4mm, 0.75mm height), with exposed paddle (EP) internally connected to SW pins and optimized for PCB heatsinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 LIN | Switched power input | Connects to inductor's input side; carries high pulsed current during MOSFET ON time. |
| 3 FB1 | High-reference feedback input | 1.2V reference when SEL = high; disabled when SEL = low or S2Cwire™ active. |
| 4 FB2 | Low-reference feedback input | 0.6V reference when SEL = low; adjustable 0.6–1.2V via S2Cwire™ rising edges. |
| 5 GND | Analog ground | Reference for internal bias and feedback comparators; separate from PGND. |
| 6–8 PGND | Power ground | Return path for boost switch current; must be low-inductance connection to input/output caps. |
| 9, 10 SW | Switching node | Drain of N-MOSFET; connects to inductor output and diode anode; high dv/dt node. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DC/DC boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61088RHLR | Fixed 500kHz frequency, requires external compensation; higher RDS(ON) (110mΩ); no S2Cwire™ or dual-FB architecture. | Lacks dynamic voltage programming; suited for fixed-output, cost-sensitive designs where layout simplicity outweighs flexibility. | Choose TPS61088RHLR only if fixed 5V output and lower component count are prioritized over programmability and light-load efficiency. |
| MAX17067ETA+ | 2.5–5.5V input; 2.5–28V output; 1.2MHz fixed-frequency; integrated Schottky; no true load disconnect or SEL/S2Cwire™. | Higher max output voltage but lacks hardware-selectable dual references and zero-output shutdown capability. | Select MAX17067ETA+ when wider output range (up to 28V) is required and thermal management permits larger solution size. |
Compared with TPS61088RHLR and MAX17067ETA+, the AAT1210IRN-0.6-T1 uniquely combines dual-reference feedback, S2Cwire™ programmability, true load disconnect, and hysteretic control - delivering superior flexibility and battery life in space-constrained portable systems requiring multiple output voltages.

FAQ
What is the purpose of the SEL pin on the AAT1210IRN-0.6-T1?
The SEL pin on the AAT1210IRN-0.6-T1 selects between two internal feedback reference voltages: logic high activates FB1 (1.2V reference), while logic low activates FB2 (0.6V reference). This enables hardware-based toggling between two output voltages across a 2.0× range - for example, 5V and 10V - without changing external resistors. When pulled low, SEL also enables S2Cwire™ mode for 16-level digital voltage programming via the EN/SET pin.
How does the AAT1210IRN-0.6-T1 achieve <1μA shutdown current?
The AAT1210IRN-0.6-T1 achieves <1μA shutdown current through its true load disconnect feature: when the EN/SET pin is pulled low, the integrated P-channel MOSFET disconnects the input from the output path, eliminating leakage through the boost diode and inductor. This ensures zero volts at VOUT and cuts total device current to 1.0μA maximum - confirmed in the Electrical Characteristics table under ISHDN test condition.
Can the AAT1210IRN-0.6-T1 operate with a 2.5V input?
No - the AAT1210IRN-0.6-T1 has a minimum input voltage of 2.7V, as specified in both the General Description and Absolute Maximum Ratings. Operation below 2.7V violates the UVLO threshold (2.7V rising, 1.8V falling) and risks improper biasing of internal circuitry. The device will remain disabled until VIN exceeds 2.7V, and sustained operation at 2.5V is not supported or characterized.
What is the maximum output voltage achievable with the AAT1210IRN-0.6-T1?
The AAT1210IRN-0.6-T1 supports a maximum output voltage of 18V, as stated in the General Description, Electrical Characteristics, and Functional Description sections. This limit applies regardless of input voltage within the 2.7–5.5V range. Output voltages above 18V are not supported and may cause overstress or malfunction due to internal voltage rating constraints.
Does the AAT1210IRN-0.6-T1 require external compensation components?
No - the AAT1210IRN-0.6-T1 uses hysteretic current-mode control, which inherently provides loop stability without external compensation components. As confirmed in the Features list and Functional Description, this architecture eliminates the need for compensation networks while delivering excellent transient response and wide operating range stability - simplifying design and reducing bill-of-materials count.
