Overview of LT8648SP

The LT8648SPJV synchronous step-down regulator adopts the second-generation ultra-low noise switching regulator architecture, minimizing EMI radiation while providing high efficiency at high switching frequencies. It includes integrated input and output capacitors to optimize all internal fast current loops and easily achieve the advertised EMI performance by eliminating layout sensitivity. This performance makes the LT8648SPJV highly suitable for noise-sensitive applications and environments.

Fast, clean and low overshoot switch edges can achieve high-efficiency operation even at high switching frequencies, thus providing a small integrated solution. Peak current mode control with a minimum on-time of 25ns enables a high step-down ratio even at high switching frequencies. External compensation through the VC pin enables a fast transient response at high switching frequencies. The VC pin also supports current sharing. By using the CLKOUT pin, other regulators can be synchronized with the LT8648SPJV.

Burst operation mode can achieve low standby power consumption, forced continuous mode can control the frequency harmonics throughout the entire output load range, or spread spectrum operation can further reduce EMI radiation.

The LT8648SPJV package features an exposed back, which can be used to install heat sinks, thereby significantly improving heat dissipation performance.
