LT8608IMSE#TRPBF from ADI is a 42V, 1.5A synchronous buck converter with ultra-low 2.5uA quiescent current in Burst Mode. 200kHz-2.2MHz adjustable frequency. 45ns min on-time. MSOP-10 with exposed pad. TRPBF = tape-and-reel, lead-free.<\/p>\n

Synchronous buck with integrated high\/low-side MOSFETs. Burst Mode operation maintains efficiency at light loads with <10mV output ripple. Peak current mode control. EN\/UV pin with 1V threshold for precision UVLO. Soft-start via TR\/SS pin. PG flag for output monitoring.<\/p>\n
