Description
The FAN5331 is a general purpose, fixed-frequency boost con-
verter designed to operate at high switching frequencies in
order to minimize switching noise measured at the battery ter-
minal of hand-held communications equipment. Quiescent cur-
rent in normal mode of operation as well as in shutdown mode
is designed to be minimal in order to extend battery life. Normal
mode of operation or shutdown mode can be selected by a logic
level shutdown circuitry.
The low ON-resistance of the internal N-channel switch ensures
high efficiency and low power dissipation. A cycle-by-cycle cur-
rent limit circuit keeps the peak current of the switch below a
maximum value of 1A. The FAN5331 is available in a 5-lead
SOT-23 package.
