Key Features
- Forced PWM mode maintains constant switching frequency across all loads, minimizing ripple-induced noise in RF and audio-sensitive designs
- 1 A output current with 0.6 V to 5.5 V adjustable output supports a broad range of processor core and I/O supply voltages from a single 5 V rail
- SOT563 package with 2.5 V to 5.5 V input range enables highly compact point-of-load regulators in space-constrained portable and wearable devices
Applications
The XLV62568APDRLT is suited for portable electronics and IoT devices that require a fixed switching frequency from no-load to full 1 A output, avoiding the frequency variation of auto-PFM converters that can interfere with RF transceivers or audio circuits. It is used to generate 1.8 V or 3.3 V processor supply rails from a 5 V USB or Li-ion input in handheld devices where PCB area is at a premium. The SOT563 footprint and current-mode PWM control also make it a reliable choice for multi-rail board designs requiring predictable EMI spectral content.

Frequently Asked Questions
What is forced PWM mode in XLV62568APDRLT and why is it important for RF designs?
Forced PWM mode keeps the XLV62568APDRLT switching at a fixed frequency regardless of load current, typically around 3 MHz. This prevents the sub-harmonic noise spurs that appear in auto-PFM converters at light loads, which can desensitize nearby RF receivers operating between 100 kHz and 10 MHz. Designers targeting 2.4 GHz or 900 MHz wireless systems benefit from predictable spectral content that is easier to filter with a small inductor and capacitor.
What output voltage range can XLV62568APDRLT produce and how is it set?
The output voltage is adjustable from 0.6 V to 5.5 V using a resistor divider connected to the FB pin. Common presets include 1.0 V for low-power FPGA core rails, 1.8 V for DDR memory, and 3.3 V for MCU I/O, all achievable with standard 1% tolerance resistors from a 3.6 V or 5 V input supply while staying within the 1 A output current rating.
How does XLV62568APDRLT perform thermally in a SOT563 package at full 1 A load?
The SOT563 package has a junction-to-ambient thermal resistance of approximately 150°C/W. At 1 A output from 5 V input to 3.3 V output, power dissipation is approximately 170 mW, yielding a junction temperature rise of about 25°C above ambient. At 25°C ambient, the junction operates at roughly 50°C, well within the -40°C to 125°C rated range, making forced airflow unnecessary in typical indoor environments.
Is XLV62568APDRLT pin-compatible with TPS62568 for sourcing flexibility?
The XLV62568APDRLT is the extended-range variant of the TPS62568 family and shares the same SOT563 6-pin footprint and pin assignments, enabling direct PCB-level substitution. Both parts deliver 1 A output with forced PWM control; the XLV prefix indicates Texas Instruments' extended product support tier, which may offer longer production commitments for high-volume designs requiring a 10-year supply guarantee.
