Description
TPS564247DRLR is Texas Instruments’ high‑efficiency synchronous buck DC‑DC regulator. It converts a higher input voltage to a lower, regulated output rail to power microprocessors and other peripherals in portable and embedded systems. The device integrates the high‑side and low‑side MOSFETs and uses fixed‑frequency, current‑mode PWM for fast transient response. An external feedback network sets the output voltage, while pins provide enable/shutdown, soft‑start, and protection features (overcurrent, thermal, undervoltage). The DRLR suffix denotes the specific package and reel/tape packaging used for manufacturing and RoHS compliance. Typical use is to generate 1.x–3.x V (or other low rails) from batteries or wall adapters with good efficiency across load conditions. For exact electrical specifications, layout guidelines, and application notes, refer to the TI product page and datasheet.
Features
TPS564247DRLR features (concise):
- 4-A synchronous buck regulator with integrated high-side and low-side MOSFETs for high efficiency
- Wide input voltage range suitable for automotive/industrial applications (typically 4.5 V to 60 V)
- Adjustable output via external feedback network; fixed-output variants available
- Enable pin, soft-start for controlled startup
- Protection: overcurrent/short-circuit, overvoltage, undervoltage lockout, and thermal shutdown
- Good load and line regulation with efficient operation across load
- Low quiescent current and favorable light-load efficiency
- RoHS-compliant, lead-free package (DRLR) suitable for compact designs
Note: For exact electrical specs (voltages, currents, switching frequency, package details), consult the TI datasheet.
