MIC2172規(guī)格書詳情
General Description
The MIC2172 and MIC3172 are complete 100kHz SMPS current-mode controllers with internal 65V 1.25A power switches. The MIC2172 features external frequency synchronization or frequency adjustment, while the MIC3172 features an enable/shutdown control input.
Although primarily intended for voltage step-up applications, the floating switch architecture of the MIC2172/3172 makes it practical for step-down, inverting, and Cuk configurations as well as isolated topologies.
Features
? 1.25A, 65V internal switch rating
? 3V to 40V input voltage range
? Current-mode operation
? Internal cycle-by-cycle current limit
? Thermal shutdown
? Low external parts count
? Operates in most switching topologies
? 7mA quiescent current (operating)
? <1μA quiescent current, shutdown mode (MIC3172)
? TTL shutdown compatibility (MIC3172)
? External frequency synchronization (MIC2172)
? External frequency trim (MIC2172)
? Fits most LT1172 sockets (see applications info)
Applications
? Laptop/palmtop computers
? Toys
? Hand-held instruments
? Off-line converter up to 50W (requires external power switch)
? Predriver for higher power capability
? Master/slave configurations (MIC2172)
