Key Features
- Wide 1.2 V to 12 V input range with output voltage up to 34 V enables versatile boost conversion for battery-powered and automotive-referenced supply designs
- Pulse Frequency Modulation (PFM) control at light loads reduces quiescent current and improves efficiency in battery-powered IoT and wearable applications
- Compact 5-pin SOT-23 package with COFF control technique minimizes external component count to just an inductor, diode, and 2 capacitors for space-constrained PCB designs
Applications
The AP3015KTR-G1 is widely used in portable battery-powered devices such as LED drivers, white LED backlights, and handheld instruments that need to boost a 1-cell lithium battery voltage (2.7 V to 4.2 V) up to 12 V to 34 V for display or RF bias rails. Its PFM light-load mode makes it ideal for IoT sensor nodes and wearables operating in sleep cycles where average current draw must remain below 10 µA. The compact SOT-23-5 footprint also suits space-constrained modules in medical monitoring devices, GPS trackers, and industrial wireless sensors requiring localized high-voltage generation.

Frequently Asked Questions
What input voltage range and maximum output voltage does the AP3015KTR-G1 support in a single-cell Li-ion boost design?
The AP3015KTR-G1 accepts input voltages from 1.2 V to 12 V, covering the full discharge range of a single-cell Li-ion battery (2.7 V to 4.2 V) and can boost the output up to 34 V. This makes it directly suitable for boosting a 3.7 V Li-ion cell to 12 V or higher for driving white LEDs, laser diodes, or TFT display bias rails without any intermediate regulation stage.
How does PFM control in the AP3015KTR-G1 extend battery life in low-duty-cycle IoT sensor applications?
In pulse frequency modulation (PFM) mode, the AP3015KTR-G1 skips switching pulses when the output load is light, reducing average switching frequency and switching losses. At output loads below 10 mA, PFM operation can reduce quiescent current to under 50 µA compared to continuous PWM operation at several milliamps, extending a 200 mAh AAA battery from a few days to several months in a sensor node sampling once per minute.
What is the minimum external component count needed to build a 3.3 V to 12 V boost converter using AP3015KTR-G1?
A minimal AP3015KTR-G1 boost circuit requires an inductor (typically 10 µH to 22 µH), a Schottky diode rated above 34 V, an output capacitor (typically 10 µF to 22 µF), an input bypass capacitor (1 µF to 10 µF), and two resistors to set the output voltage feedback divider — a total of 5 to 6 external passive components. The COFF control technique eliminates the need for compensation capacitors required by some competing boost controllers, further reducing BOM size.
For an LED backlight driver at 25 V output from a 5 V rail, is AP3015KTR-G1 a lower-cost alternative to dedicated LED driver ICs?
Yes — the AP3015KTR-G1 can function as a boost LED driver by placing the LED string (forward voltage totaling 20 V to 25 V) in series with a current-sense resistor in the output path, regulated through the feedback pin. Compared to dedicated multi-channel LED driver ICs that typically cost USD 1.00 to USD 3.00 in 1k quantities, the AP3015KTR-G1 in SOT-23-5 at under USD 0.30 per unit offers significant BOM savings for single-string backlight applications up to 34 V output.
