Product details
Overview
AP3015AKTR-G1 from BCD Semiconductor is a micro-power, PFM-controlled step-up DC-DC converter in SOT-23-5 package, designed for low-input-voltage battery-powered systems. It features 1.0V minimum input voltage, 100mA typical switching current limit, 1.23V feedback reference, and shutdown control enabling <1µA quiescent current - optimized for LCD/OLED bias and single-cell to 3.3V boost applications.
For engineers reviewing the AP3015AKTR-G1 datasheet, AP3015AKTR-G1 pinout, AP3015AKTR-G1 application, or AP3015AKTR-G1 equivalent, key selection criteria include input voltage headroom below 1.2V, fixed off-time control stability under light loads, FB-based output voltage programming, and SHDN-driven power sequencing in portable devices.
Technical Context
The AP3015AKTR-G1 implements a constant off-time (400ns nominal), current-limited PFM control architecture with internal NPN switch and bandgap-referenced feedback comparator (1.23V ±25mV, 8mV hysteresis). Its operation relies on FB voltage monitoring to enable/disable switching cycles, delivering regulated output up to 34V from inputs as low as 1.0V.
Under light load or startup, it dynamically extends off-time to 1.5µs and reduces current limit to ~70mA to minimize dissipation. The SHDN pin provides logic-level enable/disable with 0.9V high-threshold and 0.25V low-threshold, supporting system-level power gating without external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.0V to 12V - supports single alkaline/NiMH or Li-ion cell start-up without pre-bias. |
| Feedback Reference Voltage | 1.23V (±25mV) - sets output via resistor divider; enables precise programmable VOUT from 1.23V to 34V. |
| Switching Current Limit | 100mA typical - limits peak inductor current to protect internal NPN switch and external components. |
| Quiescent Current | 17µA typical (active), <1µA (shutdown) - extends battery life in always-on or intermittent-use devices. |
| Switch Saturation Voltage | 70mV at 70mA - minimizes conduction loss in low-current boost topologies. |
| Fixed Off-Time | 400ns (normal), 1.5µs (low-VFB) - ensures stable PFM operation across load range while limiting thermal stress during fault conditions. |
| SHDN Threshold | 0.9V high / 0.25V low - compatible with standard GPIO outputs and open-drain logic without level-shifting. |
Pinout & Package
SOT-23-5 package: 2.95mm × 1.70mm × 1.30mm body, 0.95mm lead pitch, gull-wing leads, green RoHS-compliant molding compound (G1 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - SW | Switch collector node | Connects to inductor and flyback diode anode; requires minimal trace area to suppress EMI and reduce parasitic inductance. |
| 2 - GND | Power and signal ground | Must tie directly to PCB ground plane for thermal dissipation and noise immunity; shared return for FB and SHDN. |
| 3 - FB | Feedback input | Monitors output via resistor divider; VOUT = 1.23V × (1 + R1/R2); short loop critical for ripple rejection and loop stability. |
| 4 - SHDN | Enable/disable control | Logic-high (>0.9V) enables regulation; logic-low (<0.25V) disables switching and drops IQ to <1µA. |
| 5 - VIN | Input supply | Accepts 1.0–12V; requires local ceramic bypass capacitor (e.g., 4.7µF X5R) placed adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low input start-up voltage | 1.0V typical - enables operation from partially discharged single-cell batteries (e.g., 1× AA/AAA). |
| Programmable output voltage | Set via external resistive divider on FB pin - supports fixed or adjustable outputs from 1.23V to 34V. |
| Dynamic off-time extension | Extends to 1.5µS when FB < 0.6V - reduces average inductor current during startup or overload to limit thermal stress. |
| Integrated NPN power switch | 70mV VCE(SAT) at 70mA - eliminates need for external transistor and simplifies layout in space-constrained designs. |
| Green RoHS-compliant packaging | G1 suffix indicates halogen-free, lead-free, and green molding compound - meets IPC/JEDEC industry environmental standards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-up DC-DC converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61099YFFR (TI) | 1.8V min VIN, 400mA switch limit, integrated diode, 1.22V FB reference | Requires ≥1.8V input; better suited for dual-cell or higher-VIN systems where efficiency above 10mA matters more than ultra-low-VIN start-up | Select when input rarely drops below 1.8V and integrated diode simplifies BOM; avoid for single-cell 1.2V–1.5V use cases. |
| MAX17222ETA+T (Maxim) | 0.4V min VIN, 500mA switch limit, 1.212V FB reference, 2.5µA IQ (active) | Starts from lower VIN but draws 5× more quiescent current; optimized for sub-1V energy harvesting rather than battery longevity | Select for ultra-low-VIN harvesting applications where 2.5µA IQ is acceptable; not recommended for long-life battery systems requiring <20µA active IQ. |
Compared with TPS61099YFFR and MAX17222ETA+T, AP3015AKTR-G1 uniquely balances 1.0V start-up, 17µA active IQ, and 100mA current limit - making it optimal for cost-sensitive, single-cell consumer devices where runtime and cold-start reliability outweigh peak efficiency or integration density.

FAQ
What is the minimum input voltage required for AP3015AKTR-G1 to start switching?
The AP3015AKTR-G1 starts switching at 1.0V typical input voltage, verified per datasheet Section 5 (Recommended Operating Conditions) and Figure 7 (Saturation Voltage vs. Junction Temperature). This allows reliable operation from nearly depleted single alkaline or NiMH cells, and is confirmed by test data showing functional regulation at 1.0V with 100mA load and 20V output.
How is output voltage set, and what tolerance does the feedback reference have?
Output voltage is set using a resistor divider from VOUT to FB and FB to GND, per VOUT = 1.23V × (1 + R1/R2). The feedback reference has a typical value of 1.23V with ±25mV (±2.0%) initial tolerance over temperature, as specified in Table 1 (Electrical Characteristics) and validated in Figure 5 (Feedback Voltage vs. Junction Temperature).
Does AP3015AKTR-G1 require external compensation components?
No external compensation components are required. The AP3015AKTR-G1 uses a fixed off-time PFM control scheme with internal compensation, enabling stable regulation with only five external parts: input/output capacitors, inductor, diode, and FB divider - as demonstrated in Figure 15 (Typical Application) and confirmed in the Application Information section.
What happens to the output during SHDN pin assertion?
When SHDN is pulled below 0.25V, the internal NPN switch turns off and quiescent current drops to <1µA. The output voltage decays to approximately VIN minus one diode forward drop (e.g., ~0.3V below VIN for Schottky), as stated in the Application Information section and verified in shutdown-mode characterization curves.
