Product details
Overview
AAT1230ITP-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 feedback reference (FB1 = 1.2V, FB2 = 0.6V). It operates from 2.7V–5.5V input and delivers regulated bias voltage for OLED displays, CCD sensors, and LCD panels in single-cell Li-ion battery systems.
For engineers reviewing the AAT1230ITP-T1 datasheet, AAT1230ITP-T1 pinout, AAT1230ITP-T1 application, or AAT1230ITP-T1 equivalent, this device supports dynamic output voltage selection via SEL logic or S2Cwire™ serial interface, features 0.35ms soft-start, <1μA shutdown current, and requires no external compensation components.
Technical Context
The AAT1230ITP-T1 implements a hysteretic current-mode control loop that directly modulates peak inductor current based on FB1/FB2 error voltage, enabling fast transient response without compensation networks. Its cycle-by-cycle current limit (3.0A typical) and over-temperature shutdown (140°C) ensure robust operation under overload and thermal stress.
It integrates a slew-rate-controlled P-channel input disconnect switch (RDS(ON) = 0.18Ω) and an N-channel power switch (RDS(ON) = 0.06Ω), supporting true load isolation when EN/SET is low. Switching frequency scales from ~400kHz to 2MHz depending on load, input voltage, and inductor value (recommended 2.2μH).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 5.5V - compatible with single-cell Li-ion (2.7–4.2V) and regulated 3.3V/5V rails |
| Max Output Voltage | 18V - sufficient for high-voltage OLED anode bias and CCD sensor supplies |
| Output Current | 100mA @ 18V - supports medium-power display and imaging bias loads |
| Switching Frequency | Up to 2MHz - enables use of ultra-small 2.2μH inductors and reduces solution footprint |
| Efficiency | Up to 85% at full load - maintains high conversion efficiency across 10V–18V outputs |
| Shutdown Current | <1μA - preserves battery life during system sleep modes |
| Soft-Start Time | 0.35ms - monotonic startup prevents output overshoot and minimizes inrush |
Pinout & Package
Package: TSOPJW-12 (3.0 × 3.0 × 0.8 mm, Pb-free, thermally enhanced).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VP | Input power supply node | Connects to source of internal P-MOSFET; ties to input capacitor(s) for low-impedance VIN path |
| EN/SET | Enable / S2Cwire™ data pin | Active-high enable; doubles as single-wire serial interface input when SEL = low |
| SEL | Feedback select logic input | High → activates FB1 (1.2V ref); Low → activates FB2 (0.6V ref) or enables S2Cwire mode |
| VIN | Main input voltage rail | Direct connection to VP; powers internal bias circuitry and UVLO detection |
| N/C | No connection | Pin 5 in TSOPJW-12 - must be left floating or grounded per layout guidelines |
| SW | Switching node | Drain of internal N-MOSFET; connects to inductor and Schottky diode anode |
| LIN | Inductor return node | Connects to inductor's ground-side terminal; tied internally to SW during OFF time |
| FB1 | High-reference feedback input | 1.2V precision reference; active only when SEL = high; sets higher output voltage level |
| FB2 | Low-reference feedback input | 0.6V precision reference; active only when SEL = low; enables 2× output range flexibility |
| GND | Analog ground | Reference for FB1/FB2 comparators and internal logic; separate from PGND for noise isolation |
| PGND | Power ground | Source of internal N-MOSFET; returns high-current switching paths to minimize ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| Hysteretic control architecture | Eliminates need for external compensation components and guarantees stable operation across all loads |
| True load disconnect | Isolates output from input when disabled, reducing leakage to zero and holding VOUT = 0V |
| Dual feedback reference (FB1/FB2) | Enables dynamic 2× output voltage range selection (e.g., 12V ↔ 18V) using one GPIO |
| S2Cwire™ serial interface | 16-level programmable output voltage via single-wire EN/SET pin - no additional I/O required |
| Integrated soft-start | 0.35ms monotonic ramp prevents output overshoot and limits inrush current into output capacitors |
| Cycle-by-cycle current limit | 3.0A peak current protection ensures safe operation during short-circuit or overload conditions |

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; 28V internal switch; no true load disconnect; requires external compensation | Lacks dual-reference feedback and S2Cwire™; better suited for fixed-output, non-battery-critical systems | Select when 28V capability is needed and SEL/S2Cwire™ programmability is unnecessary |
| MAX17062ETA+ | 16V max output; integrated Schottky; 1.2MHz fixed-frequency PWM; no hysteretic control | Lower max output voltage; less optimal for 18V OLED/CCD; higher light-load quiescent current (~15μA) | Prefer when EMI-sensitive environments require fixed-frequency operation and integrated diode simplifies layout |
Compared with TPS61040DRVR and MAX17062ETA+, the AAT1230ITP-T1 uniquely combines 18V capability, true load disconnect, dual-reference feedback, and S2Cwire™ programmability in a 12-pin TSOPJW package - making it optimal for space-constrained, battery-powered imaging and display bias applications requiring dynamic voltage control.

FAQ
What is the maximum output voltage supported by the AAT1230ITP-T1?
The AAT1230ITP-T1 supports a maximum output voltage of 18V. This rating is guaranteed across the full operating temperature range (–40°C to +85°C) and input voltage range (2.7V to 5.5V), making it suitable for high-voltage OLED anode bias and CCD sensor applications. The device achieves this using an integrated N-channel MOSFET with 20V absolute maximum SW node rating and optimized hysteretic control loop stability.
Does the AAT1230ITP-T1 include true load disconnect functionality?
Yes, the AAT1230ITP-T1 provides true load disconnect: when the EN/SET pin is pulled low, the internal P-channel input disconnect switch opens, isolating the output from the input rail. This eliminates leakage current and holds the output voltage at 0V, which is essential for battery-powered systems requiring zero standby power. The feature is implemented with a dedicated slew-rate controlled MOSFET and does not rely on external components.
How does the AAT1230ITP-T1 achieve dynamic output voltage selection?
The AAT1230ITP-T1 supports dynamic output voltage selection via two methods: (1) logic-level SEL pin toggling between FB1 (1.2V reference) and FB2 (0.6V reference) for coarse 2× range adjustment; and (2) S2Cwire™ serial interface on the EN/SET pin for fine-grained 16-level programming across the same range. Both methods require no additional pins or external controllers, and the AAT1230ITP-T1 handles all timing and decoding internally.
What is the soft-start time of the AAT1230ITP-T1, and how is it configured?
The AAT1230ITP-T1 has a fixed soft-start time of 0.35ms - the time from EN/SET high-to-low transition to regulated output voltage. This value is inherent to the AAT1230 variant (as opposed to the AAT1230-1's 3.5ms) and is implemented by internal timing circuitry. No external components are required to configure or adjust it, ensuring monotonic startup and eliminating output overshoot across all input voltages and load conditions.
Which package does the AAT1230ITP-T1 use, and what are its thermal characteristics?
The AAT1230ITP-T1 uses the TSOPJW-12 package (3.0 × 3.0 × 0.8 mm, Pb-free). Its thermal resistance θJA is 160°C/W, and maximum power dissipation at TA = 25°C is 625 mW. The exposed paddle is not electrically connected but enhances thermal conduction to the PCB. Layout best practices include soldering the EP pad to a thermal copper plane and separating PGND and GND traces to maintain signal integrity.
