Product details
Overview
AAT2713IVN-AA-T1 from Skyworks Solutions is a dual synchronous step-down DC-DC converter optimized for low-noise, high-efficiency power delivery in battery-powered portable electronics. It delivers 600mA per channel across 2.7V–5.5V input, features 1.7MHz fixed-frequency PWM operation, 180° phase-shift capability via PS pin, and achieves 96% peak efficiency with 70μA total no-load quiescent current - enabling extended runtime in smartphones and handheld instruments.
For engineers reviewing the AAT2713IVN-AA-T1 datasheet, AAT2713IVN-AA-T1 pinout, AAT2713IVN-AA-T1 application, or AAT2713IVN-AA-T1 equivalent, key selection criteria include dual-channel independent enable control (EN1/EN2), MODE/SYNC logic-selectable light-load vs. low-noise PWM mode, thermal shutdown at 140°C, and QFN33-16 package compatibility with tight PCB layout constraints for noise-sensitive RF and analog subsystems.
Technical Context
The AAT2713IVN-AA-T1 implements peak-current-mode PWM control with internal compensation per channel, supporting independent feedback (FB1/FB2) and input rails (VIN1/VIN2). Its architecture enables 100% duty-cycle low-dropout operation and integrates P-channel (RDS(ON)H = 0.45Ω) and N-channel (RDS(ON)L = 0.40Ω) synchronous MOSFETs per channel.
Phase synchronization is configurable via PS pin (logic-high forces 180° out-of-phase operation to halve input ripple) and external clock injection on MODE/SYNC pin. UVLO triggers at 2.35V falling and 2.7V rising, while over-temperature protection activates at 140°C with 15°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 5.5V - supports single-cell Li-ion/polymer battery systems without pre-regulation. |
| Output Current per Channel | 600mA - sufficient for microprocessor core/IO rails, camera sensor bias, or DSP subsystems. |
| Switching Frequency | 1.7MHz typical - enables use of compact 2.2μH–4.7μH inductors and reduces EMI filtering burden. |
| No-Load Quiescent Current | 70μA total for both channels - minimizes standby power loss in always-on mobile applications. |
| Efficiency | 96% peak - achieved at full load with optimized MOSFET RDS(ON) and synchronous rectification. |
| Feedback Reference Voltage | 0.600V ±9mV - enables precise output regulation from 0.6V to VIN using external resistor dividers. |
| Thermal Protection | 140°C shutdown with 15°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
Pinout & Package
The AAT2713IVN-AA-T1 is housed in a Pb-free, thermally enhanced 16-pin QFN33 package (3mm × 3mm, 0.5mm pitch) with exposed paddle for improved thermal dissipation. Package dimensions and soldering profile comply with JEDEC MO-220 standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PS | Phase shift control | Logic-high forces 180° out-of-phase operation between converters to reduce input ripple by ~50%. |
| AGND | Analog ground reference | Return node for FB1/FB2 resistive dividers; must be isolated from noisy PGND planes per layout guidelines. |
| FB1, FB2 | Output voltage feedback inputs | Accept 0.6V reference; configure output voltage up to VIN using external resistor dividers (e.g., 59kΩ/88.5kΩ for 1.5V). |
| VIN1, VIN2 | Independent input supplies | Support separate battery or rail inputs per channel; require local 1μF ceramic decoupling each. |
| EN1, EN2 | Channel enable controls | Logic-high enables respective converter; logic-low shuts down channel to <1μA supply current. |
| VCC | Internal bias supply | Powered from higher of VIN1 or VIN2; supplies control circuitry and must be stable before enable. |
| MODE/SYNC | Operating mode select / sync input | Logic-low enables light-load + PWM hybrid mode; logic-high forces low-noise PWM; accepts external 1.7MHz clock. |
| LX1, LX2 | Power switch node outputs | Connect to respective inductors; require low-ESR/ESL routing to minimize switching losses and EMI. |
| PGND1, PGND2 | Power ground returns | Separate return paths for each channel's input/output capacitors; tie to AGND only at single point near IC. |
| N/C (Pins 6, 15) | No-connect terminals | Must remain unconnected; not internally bonded or electrically active. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise light-load mode | Reduces spectral noise and output ripple during standby/sleep states without sacrificing regulation accuracy. |
| 180° phase-shift capability | Halves input capacitor RMS current and peak-to-peak ripple, enabling smaller, lower-cost input filtering. |
| Integrated synchronous MOSFETs | Eliminates need for external diodes; P/N-channel pair per channel achieves 96% efficiency at full load. |
| Automatic soft-start | Prevents output overshoot and limits inrush current during power-up or enable assertion. |

|---|---|---|---|
| Texas Instruments TPS62400DRCR | 2.5V–6.0V input; 600mA/channel; 2.25MHz switching; no phase-shift pin; requires external compensation. | Lacks PS pin for input ripple reduction; higher fSW demands smaller inductors but increases switching losses at high VIN. | Choose when board space is constrained and input ripple is managed externally; avoid if 180° phase alignment is required for EMI compliance. |
| Analog Devices ADP5052ACPZ | 2.7V–5.5V input; 600mA/channel; 1.2MHz switching; integrated LDO on second channel; no MODE/SYNC flexibility. | Includes 300mA LDO for noise-sensitive analog rails; fixed 1.2MHz limits inductor size options; no light-load PWM mode. | Prefer when mixed buck+LDO regulation is needed; not suitable for applications requiring dynamic light-load efficiency optimization. |
Compared with TPS62400DRCR and ADP5052ACPZ, the AAT2713IVN-AA-T1 uniquely combines 180° phase-shift control, logic-selectable light-load/PWM modes, and 70μA quiescent current - making it optimal for battery-constrained portable devices where input ripple, standby power, and transient noise are co-optimized.

FAQ
What input voltage range does the AAT2713IVN-AA-T1 support, and why is this important for portable designs?
The AAT2713IVN-AA-T1 supports an input voltage range of 2.7V to 5.5V, which aligns precisely with the discharge profile of single-cell lithium-ion or lithium-polymer batteries. This eliminates the need for intermediate pre-regulators in smartphones, tablets, and handheld instruments, reducing bill-of-materials cost and PCB area. The 2.7V lower limit ensures continued operation until battery depletion, while the 5.5V upper limit accommodates USB-powered operation and transient surges without external clamping.
How does the PS pin on the AAT2713IVN-AA-T1 reduce input ripple, and what design impact does this have?
The PS pin on the AAT2713IVN-AA-T1 enables 180° out-of-phase operation between the two converters when driven high, causing their input current pulses to cancel partially. This reduces peak-to-peak input ripple by approximately 50%, allowing designers to use smaller, lower-cost ceramic input capacitors (e.g., 2×10μF X5R) instead of larger bulk electrolytics. In practice, this simplifies layout, lowers EMI emissions, and improves system-level power integrity - especially critical in RF-dense smartphone mainboards.
What is the significance of the 70μA total no-load quiescent current specified for the AAT2713IVN-AA-T1?
The 70μA total no-load quiescent current for the AAT2713IVN-AA-T1 represents the combined bias current drawn by both channels when disabled or under zero load, directly extending battery runtime in always-on or sleep-mode applications. For example, in a smartphone with two AAT2713IVN-AA-T1 rails powering standby peripherals, this ultra-low IQ contributes less than 0.5% daily battery drain - a critical advantage over alternatives drawing >200μA, particularly in devices with multi-week standby requirements.
Can the AAT2713IVN-AA-T1 operate with different output voltages on each channel, and how is this configured?
Yes, the AAT2713IVN-AA-T1 supports independent output voltages per channel using separate FB1 and FB2 feedback networks. Each output is set by an external resistor divider referenced to the 0.600V internal bandgap - for instance, 59kΩ and 88.5kΩ resistors yield 1.5V on Channel 1, while 59kΩ and 113kΩ set 1.8V on Channel 2. This flexibility enables simultaneous core (1.2V), I/O (2.5V), and analog (3.3V) rail generation from a single IC, reducing component count and improving power sequencing control in complex portable SoC platforms.
What protection features are built into the AAT2713IVN-AA-T1, and how do they enhance system reliability?
The AAT2713IVN-AA-T1 integrates current-limit protection (1.5A per channel), over-temperature shutdown (140°C with 15°C hysteresis), and under-voltage lockout (UVLO at 2.35V falling). These features prevent catastrophic failure during short circuits, thermal runaway, or brownout conditions. For example, during a camera sensor short, the 1.5A current limit clamps fault energy, while thermal shutdown disables both channels before junction temperature exceeds safe limits - ensuring field-reliability in unattended portable deployments without external supervision circuitry.
