Buck Switching Regulator IC Positive Adjustable (Fixed) 0.8V (3.3V, 5V) 1 Output 4.5A 20-WFQFN Exposed Pad The LM656x5-Q1 are a family of automotive buck converters designed for high efficiency, high-power density, and ultra-low electromagnetic interference (EMI). The converters operate over a wide input voltage range of 3V to 65V (70V transient < 100ms), reducing the need for external input surge protection. The LM656x5-Q1 comes with pin selectable fixed output voltages of 3.3V and 5V or in adjustable configuration. The low EMI operation is enabled with minimized loop inductance and optimized switch node slew rate. A pin-selectable ±5% or ±10% dual-random spread spectrum (DRSS) significantly reduces peak emissions through a combination of triangular and pseudo-random modulation while keeping output voltage ripple very low. The current-mode control architecture with a 30ns typical minimum on-time allows high conversion ratios at high frequencies coupled with a fast transient response and excellent load and line regulation.

The NCP1345, manufactured by onsemi, is a highly integrated quasi-resonant flyback controller optimized for high-performance off-line USB-PD and USB Type-C power converters. This advanced controller features a dual-pin Vcc architecture for simplified Vcc management and enhanced performance, allowing direct connection to the auxiliary winding. It incorporates a precise primary side-based output current limiting circuit to ensure a constant output current limit irrespective of the programmed output voltage or nameplate output power. The quasi-resonant (QR) current-mode flyback stage is equipped with proprietary valley-lockout circuitry for stable valley switching down to the 6th valley and transitions to frequency foldback mode to reduce switching losses. Additional load decreases trigger the NCP1345 to enter skip mode for efficient power management. Key protective features include internal brownout detection, maximum output current limit, latched overvoltage, and NTC-ready overtemperature protection, as well as line removal detection for safe discharge of X2 capacitors. The NCP1345 is available in SOIC-9 NB packages and supports various configurations and protection mechanisms, making it a robust solution for modern power supply designs.
