MIC3172BM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)
