Product details
Overview
AAT1230IRN-1-T1 from Skyworks Solutions is a 18V, 100mA step-up DC/DC converter with hysteretic control, integrated P- and N-channel MOSFETs, true load disconnect, and dual FB reference selection (FB1 = 1.2V, FB2 = 0.6V). It operates from 2.7V–5.5V input and delivers regulated output for OLED/LCD bias in single-cell Li-ion systems.
For engineers reviewing the AAT1230IRN-1-T1 datasheet, AAT1230IRN-1-T1 pinout, AAT1230IRN-1-T1 application, or AAT1230IRN-1-T1 equivalent, this page provides verified technical context, package mapping to TDFN34-16, confirmed soft-start time of 3.5ms, validated S2Cwire programmability via EN/SET, and real-world design meaning for load transient response, efficiency at light load, and thermal protection behavior.
Technical Context
The AAT1230IRN-1-T1 implements a hysteretic current-mode control loop with no external compensation required, enabling up to 2MHz switching and fast load transient response. Its cycle-by-cycle current limit (3.0A typical) and over-temperature shutdown (140°C, 15°C hysteresis) operate independently of feedback configuration.
Output voltage is set either statically via SEL pin logic (FB1=1.2V or FB2=0.6V), dynamically between two levels by toggling SEL, or across 16 levels using S2Cwire serial protocol on EN/SET - all while maintaining true load disconnect when EN/SET is low, eliminating leakage and holding zero output voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOUT Max | 18V - supports high-voltage bias for CCD, OLED, and LCD panels from 3.6V Li-ion source. |
| IOUT | 100mA - sufficient for display bias and sensor supply in portable imaging devices. |
| VIN Range | 2.7V to 5.5V - compatible with fully discharged to overcharged single-cell Li-ion batteries. |
| TSS | 3.5ms - slower soft-start reduces inrush current in high-impedance battery systems. |
| Efficiency | Up to 85% - achieved with integrated low-RDS(ON) MOSFETs (RDS(ON)L = 60mΩ, RDS(ON)IN = 180mΩ) and pulsed-frequency operation at light load. |
| Shutdown IQ | <1μA - enables zero-power standby in always-on display subsystems. |
| Operating Temp | −40°C to +85°C - qualified for industrial and mobile handset environments. |
Pinout & Package
Package: Thermally enhanced Pb-free 16-pin TDFN34-16 (3mm × 4mm, 0.5mm pitch), exposed paddle tied to SW pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VP | Input power source connection | Connects to input capacitor(s); ties to VIN internally - must be low-inductance path for P-MOSFET source. |
| EN/SET | Enable / S2Cwire serial data input | Active-high enable; when SEL = low, accepts S2Cwire clock/data for 16-level output programming. |
| SEL | Feedback reference selector | High → enables FB1 (1.2V ref); low → enables FB2 (0.6V ref) or activates S2Cwire mode. |
| VIN | Converter input voltage rail | Directly connected to VP; supplies internal bias circuits and UVLO detection (2.7V threshold). |
| N/C | No connection | Pin 5 in TSOPJW-12; not bonded in TDFN34-16 - leave unconnected. |
| SW | Switching node | Drain of N-MOSFET and anode of external Schottky diode; high dv/dt node requiring tight layout. |
| PGND | Power ground return | Source of N-MOSFET; connects to input/output capacitor grounds - separate from signal GND. |
| GND | Signal ground reference | Reference for FB1/FB2 comparators and internal logic - connect near PGND with short trace. |
| FB1 | High-reference feedback input | 1.2V ±3.6% reference when SEL = high; disabled otherwise - sets higher output voltage tier. |
| FB2 | Low-reference feedback input | 0.6V ±3.6% reference when SEL = low; disabled otherwise - sets lower output voltage tier or S2Cwire base. |
| LIN | Inductor connection node | Connected to inductor free end; non-switching node - suitable for PCB heatsinking without EMI penalty. |
Key Features
| Feature | Design Value |
|---|---|
| True load disconnect | Isolates output from input when EN/SET = low, eliminating leakage and ensuring zero VOUT - critical for display sleep modes. |
| Hysteretic control | Enables 2MHz max switching with no external compensation, delivering <200µs load transient recovery and stable operation with 2.2µH inductors. |
| Dual FB reference selection | SEL pin selects between 1.2V (FB1) and 0.6V (FB2) references - enables dynamic 2× output range switching (e.g., 12V ↔ 18V) without firmware change. |
| S2Cwire interface | Single-wire serial protocol on EN/SET pin allows 16-step programmable output voltage across full 2× range - replaces resistor networks in adaptive bias applications. |
| Integrated soft start | 3.5ms monotonic ramp (AAT1230IRN-1-T1 variant) prevents overshoot and limits inrush into large output capacitors - ideal for battery-powered cameras. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61040DRVR | Fixed 28V max output; no dual-FB or S2Cwire; 500kHz fixed-frequency PWM control. | Lacks dynamic voltage selection and true load disconnect - requires external MOSFET for output isolation. | Choose for cost-sensitive, fixed-output applications where hysteretic response and programmability are unnecessary. |
| MAX8647ETE+ | 15V max output; 1.2MHz fixed frequency; integrated 1.2V LDO; no S2Cwire or SEL-based dual reference. | Designed for PMIC integration in handhelds - includes LDO but lacks high-voltage capability and true disconnect. | Prefer when co-locating with other power rails and needing integrated LDO, but not for >15V bias generation. |
Compared with TPS61040DRVR and MAX8647ETE+, the AAT1230IRN-1-T1 uniquely combines 18V capability, dual-reference flexibility, S2Cwire programmability, and zero-leakage load disconnect - making it optimal for adaptive display bias where voltage agility and standby integrity are mandatory.

FAQ
What is the soft-start time of the AAT1230IRN-1-T1?
The AAT1230IRN-1-T1 has a fixed soft-start time of 3.5ms - measured from EN/SET low-to-high transition to regulated output voltage. This longer ramp reduces inrush current in battery-powered systems with high source impedance, distinguishing it from the 0.35ms AAT1230IRN variant.
Does the AAT1230IRN-1-T1 support dynamic output voltage adjustment?
Yes, the AAT1230IRN-1-T1 supports three methods: static selection via SEL pin (FB1=1.2V or FB2=0.6V), dynamic toggling between two voltages using SEL, or 16-level programmability via S2Cwire serial protocol on the EN/SET pin - all without external DACs or microcontroller intervention.
How does the true load disconnect feature work in the AAT1230IRN-1-T1?
When EN/SET is pulled low, the AAT1230IRN-1-T1 disables both power MOSFETs and activates an internal slew-rate-controlled input disconnect switch. This isolates the output from the input, eliminating leakage current and holding VOUT at 0V - essential for display sleep modes and system-level power gating.
What package does the AAT1230IRN-1-T1 use, and how is thermal performance managed?
The AAT1230IRN-1-T1 uses a thermally enhanced Pb-free TDFN34-16 package (3mm × 4mm) with an exposed paddle tied to SW pins. Its θJA is 44°C/W, enabling 2270mW max power dissipation at 25°C ambient - supported by direct PCB copper pour under the exposed pad and LIN-node heatsinking.
What protection features are built into the AAT1230IRN-1-T1?
The AAT1230IRN-1-T1 integrates cycle-by-cycle current limiting (3.0A typical), over-temperature shutdown (140°C with 15°C hysteresis), under-voltage lockout (2.7V rising threshold), and short-circuit protection. All functions operate autonomously without external components and recover automatically upon fault removal.
