LT8648SHV#PBF

LT8648SHV#PBF is a high-voltage, wide-input-range synchronous DC-DC regulator from Analog Devices (formerly Linear Technology). The SHV variant is the high-voltage version, and #PBF denotes the lead-free, RoHS-compliant plastic package option. It integrates the input and output MOSFETs (high-side and low-side) and is designed to convert a broad range of input voltages to a stable, lower output with high efficiency.
Key points:
- Wide input range (HV version) suitable for automotive and industrial supplies
- Synchronous switching regulator with integrated MOSFETs (no external FETs required)
- Adjustable output via resistor network; supports soft-start and enable/shutdown
- Protection features such as overcurrent protection, thermal shutdown, and undervoltage lockout
- Typical use: pre-regulation or main DC-DC conversion from high-voltage sources to a regulated lower voltage
For detailed electrical specs, recommended layouts, and application circuits, refer to the LT8648SHV datasheet and design notes.

Here are the typical features of LT8648SHV#PBF (high‑voltage, automotive‑grade buck/boost controller with integrated FETs and PBF package):
- Wide input voltage range: up to 60V
- Synchronous controller with integrated high‑ and low‑side MOSFETs
- Fixed or adjustable switching frequency (programmable, up to a few MHz)
- Current‑mode PWM control with fast transient response
- Adjustable output voltage via feedback resistors; robust regulation
- Enable/disable control and undervoltage lockout (UVLO)
- Overcurrent/short‑circuit protection with cycle‑by‑cycle current limiting
- Overtemperature protection
- Soft‑start and output voltage tracking
- Remote sense capability for accurate regulation
- Optional fault and status indicators
- Suitable for automotive/industrial environments (SHV) with extended temp range
