Key electrical and mechanical differences between the two devices
| Parameter | AP3032KTR-G1 | AP3036KTR-G1 | Why it matters |
|---|---|---|---|
| Number of Output Channels | 1 | 1 | Both are single-channel boost converters, so channel count does not differentiate them for substitutability. |
| Input Voltage Range | 2.5 V to 5.5 V | 2.5 V to 5.5 V | Matching input ranges allow the parts to operate from the same supply rails in a given design. |
| Output Voltage (max) | Up to 27 V | Up to 27 V | The maximum boost output voltage determines the LED string or load the converter can drive. |
| Switching Frequency | 1.2 MHz | 1.2 MHz | Switching frequency affects inductor/capacitor sizing and EMI; identical values ease drop-in replacement. |
| Switch Current Limit | 1.4 A (typ) | 1.4 A (typ) | Current limit sets the maximum deliverable load current and influences inductor selection. |
| Feedback Voltage | 0.2 V (typ) | 0.2 V (typ) | Feedback reference voltage determines LED current setting via the sense resistor; matching values allow identical current programming. |
| Package | SOT-23-6 | SOT-23-6 | Same package footprint enables direct PCB drop-in substitution without layout changes. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Identical temperature ratings ensure equivalent environmental robustness for the application. |

Frequently asked questions
What are the AP3032KTR-G1 and AP3036KTR-G1?
The AP3032KTR-G1 and AP3036KTR-G1 are step-up (boost) DC-DC converters from Diodes Incorporated designed for driving white LEDs in backlighting applications. Both are offered in the SOT-23-6 package and operate from a low input voltage, making them suitable for portable and battery-powered devices.
What is the key difference between the AP3032KTR-G1 and AP3036KTR-G1?
The primary difference is the LED current capability and the associated feedback reference. The AP3032KTR-G1 is specified for a lower LED drive current, while the AP3036KTR-G1 supports a higher LED current. Designers should confirm the exact current rating and feedback voltage from the respective Diodes Incorporated datasheets before selecting between the two.
Do the AP3032KTR-G1 and AP3036KTR-G1 share the same package and pinout?
Yes. Both devices are supplied in the SOT-23-6 package and use the same pin configuration, which allows them to share a common PCB land pattern. However, pin compatibility does not guarantee electrical interchangeability, so the surrounding components must be validated for the selected part.
Can the AP3032KTR-G1 and AP3036KTR-G1 be used interchangeably in the same design?
Not automatically. Although they share the same package and pinout, the difference in LED current capability and feedback reference means the current-setting resistor and inductor must be recalculated for each device. Interchangeability should only be confirmed after verifying all parameters against the manufacturer datasheets and validating the target design.
What input voltage range do the AP3032KTR-G1 and AP3036KTR-G1 support?
Both devices are designed for low-voltage step-up operation suitable for single-cell Li-ion or multi-cell alkaline battery applications. The exact minimum and maximum input voltage limits, as well as the maximum output voltage, should be taken directly from the Diodes Incorporated datasheet for each part number, as these limits govern the safe operating area.
What is the switching frequency of the AP3032KTR-G1 and AP3036KTR-G1?
Both converters use a fixed high-frequency switching architecture that allows the use of small external inductors and capacitors. The specific switching frequency value should be confirmed from the official Diodes Incorporated datasheet for each device, since it affects inductor selection, output ripple, and EMI performance.
What protection features are included in the AP3032KTR-G1 and AP3036KTR-G1?
Both devices integrate protection functions typical of LED boost converters, including over-voltage protection at the output and cycle-by-cycle current limiting. The exact thresholds and behaviors are defined in the manufacturer datasheet and should be reviewed to ensure they meet the reliability requirements of the target application.
Which applications are the AP3032KTR-G1 and AP3036KTR-G1 intended for?
These converters are intended for white LED backlighting in portable electronics such as smartphones, tablets, GPS units, and other handheld devices, as well as general LED lighting where a compact step-up driver is required. Selection between the two should be based on the required LED current and the corresponding external component values.
