Product details
Overview
AP3015KTR-G1 from BCD Semiconductor is a micro-power, pulse-frequency-modulated (PFM) step-up DC-DC converter in SOT-23-5 package, designed for battery-powered systems requiring high efficiency at light loads. It features 1.2V minimum input voltage, 350mA switching current limit, 200mV typical VCE(SAT) at 300mA, and supports output voltages up to 34V - used in LCD/OLED bias supply and portable communication devices.
For engineers reviewing the AP3015KTR-G1 datasheet, AP3015KTR-G1 pinout, AP3015KTR-G1 application, or AP3015KTR-G1 equivalent, key selection criteria include low-quiescent-current operation (17µA active, <1µA shutdown), fixed off-time control architecture, feedback voltage accuracy (1.23V ±25mV), and SOT-23-5 thermal performance (RθJA = 265°C/W).
Technical Context
The AP3015KTR-G1 implements a constant off-time PFM control scheme with internal 400ns one-shot timing and dual-threshold feedback comparator (1.23V reference with 8mV hysteresis). Its NPN power switch is current-limited to 350mA typical and features low saturation voltage for minimal conduction loss.
Startup and short-circuit protection are handled by dynamic off-time extension (to 1.5µs) and reduced current limit (~250mA) when FB voltage drops below 0.6V. The SHDN pin enables full system-level power gating with sub-1µA shutdown current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.2V to 12V - supports single-cell Li-ion (2.5–4.2V) and multi-cell alkaline/NiMH (1.2–9V) inputs without external LDO pre-regulation. |
| Feedback Reference Voltage | 1.23V ±25mV - sets output via resistor divider; enables precise 20V bias generation (e.g., R1=2MΩ, R2=130kΩ) for OLED displays. |
| Switching Current Limit | 350mA typical - defines maximum inductor peak current; determines power capability and thermal margin in boost topology. |
| VCE(SAT) @ 300mA | 200mV typical - reduces conduction loss in internal NPN switch, improving efficiency at medium load currents. |
| Quiescent Current | 17µA typical (active), <1µA (shutdown) - extends battery life in always-on or intermittent-use portable devices. |
| Switch Off-Time | 400ns fixed - determines minimum switching period; enables high-frequency operation (>1MHz under light load) with small external components. |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade handheld and consumer electronics environments. |
Pinout & Package
SOT-23-5 package (2.95mm × 1.70mm × 1.30mm, 0.95mm lead pitch), thermally optimized with exposed pad not present; RθJA = 265°C/W, RθJC = 52°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - SW | Switch node | Collector of internal NPN power transistor; connects to inductor and flyback diode anode - requires minimized trace area to reduce EMI radiation. |
| 2 - GND | Ground reference | Power and signal ground return; must connect directly to PCB ground plane for stable regulation and thermal dissipation. |
| 3 - FB | Feedback input | Senses output voltage via resistor divider; regulates VOUT = 1.23V × (1 + R1/R2); loop must be routed short and away from noisy nodes. |
| 4 - SHDN | Enable/disable control | Logic-level input: >0.9V enables converter, <0.25V forces shutdown; draws only 2–12µA, enabling low-power system wake/sleep control. |
| 5 - VIN | Power input | Main supply input (1.2–12V); requires local 4.7µF ceramic bypass capacitor placed adjacent to pin to suppress input ripple and supply transients. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed off-time PFM control | 400ns off-time ensures predictable switching frequency scaling with load - simplifies EMI filtering and enables ultra-low IQ operation at light loads. |
| Low VCE(SAT) NPN switch | 200mV at 300mA minimizes conduction loss - improves efficiency by ~3–5% over comparable 300–500mV-saturation devices in 20V bias applications. |
| Programmable output voltage | 1.23V feedback reference with 8mV hysteresis enables stable 3.3V–34V outputs using standard resistor values - no external reference needed. |
| Integrated short-circuit protection | Automatic 1.5µs off-time extension and current limit reduction below 0.6V FB voltage prevents thermal runaway during startup or output overload. |
| Green RoHS-compliant packaging | G1 suffix denotes halogen-free, lead-free, green molding compound - meets IPC/JEDEC J-STD-020C reflow profile and environmental compliance requirements. |
Applications
| MP3/MP4 Player Power Supply | LCD/OLED Display Bias |
|---|---|
Use Scenario: Boosting single-cell Li-ion (3.0–4.2V) to 20V for white LED backlight or OLED pixel driver rails. IC Role / Device Role / Timing Role: Primary step-up regulator with programmable feedback and shutdown control - manages power sequencing and sleep-mode current draw.

Use Value: Fixed 400ns off-time and 1.23V reference ensure ±1.5% output accuracy over temperature; low VCE(SAT) reduces thermal stress on PCB. |
| Battery-Powered Handheld Devices | Portable Communication Equipment |
Use Scenario: Providing regulated 5V or 12V rail from 1.5V alkaline cells in barcode scanners or portable medical sensors. IC Role / Device Role / Timing Role: Primary DC-DC power stage - interfaces with microcontroller GPIO via SHDN pin for on-demand power activation. Use Value: 1.2V start-up capability enables operation down to near-dead battery; <1µA shutdown current eliminates standby drain in sleep states. | Use Scenario: Supplying 3.3V or 5V to RF front-end ICs or baseband processors in Bluetooth headsets or walkie-talkies. IC Role / Device Role / Timing Role: Efficient boost converter with integrated current limiting - protects against antenna mismatch or RF amplifier surge currents. Use Value: 350mA current limit and thermal protection prevent latch-up during transmit bursts; SOT-23-5 footprint saves board space in compact enclosures. |
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 |
|---|---|---|---|
| AP3015AKTR-G1 | 100mA switching current limit, 1.0V min input, 70mV VCE(SAT) at 70mA | Optimized for ultra-low-power 3.3V boost (e.g., 1–2 cell to 3.3V), not suitable for >15V outputs or >200mA loads | Select when output current ≤70mA and input can drop to 1.0V - trades power capability for lower quiescent current at light loads. |
| TPS61099YFFR | 1.8V–5.5V input, 300mA limit, 0.55V dropout LDO mode, integrated soft-start | Requires higher minimum input; lacks 34V output capability but offers tighter VREF (1.212V ±0.5%) and IQ = 300nA | Prefer for battery-powered IoT sensors needing nanowatt shutdown and tight regulation - not viable for high-VOUT bias supplies. |
Compared with AP3015AKTR-G1 and TPS61099YFFR, the AP3015KTR-G1 uniquely balances 1.2V start-up, 34V output capability, and 350mA drive in SOT-23-5 - making it optimal for LCD/OLED bias where both low-VIN and high-VOUT are required simultaneously.

FAQ
What is the minimum input voltage required for AP3015KTR-G1 to start switching?
The AP3015KTR-G1 begins switching at 1.2V typical input voltage, with guaranteed operation down to 1.0V under certain conditions. This enables direct use with partially discharged alkaline or NiMH cells, eliminating need for pre-regulation stages in low-power portable designs.
How does the SHDN pin behave during power-up and system reset?
The SHDN pin must be pulled above 0.9V to enable operation; below 0.25V disables the device and reduces quiescent current to <1µA. During power-up, if SHDN is left floating or weakly biased, the device may enter undefined state - a pull-up resistor to VIN or controlled GPIO is recommended for deterministic behavior.
Can AP3015KTR-G1 regulate output voltages above 20V reliably?
Yes - the AP3015KTR-G1 supports output voltages up to 34V, verified in typical applications like LCD bias (20V) and OLED anode supplies (25–30V). Stability requires proper layout: short FB trace, low-ESR output capacitor (≥1µF X5R/X7R), and Schottky diode rated ≥40V reverse voltage.
What thermal derating applies when operating at 350mA continuous output current?
At 350mA peak switch current and 85°C ambient, junction temperature rise is ~93°C (PD ≈ 0.105W × 265°C/W), reaching ~178°C - exceeding 150°C absolute max. Derate output current to ≤250mA or add copper pour and airflow to maintain TJ < 125°C for reliable long-term operation.
