General Description
The TC170 offers maximum supply current of 3.8mA.
Bipolar current-mode control integrated circuits require
five times more operating current.
The dual totem-pole CMOS outputs drive power
MOSFETs or bipolar transistors. The 50nsec typical
output rise and fall times (1000pF capacitive loads)
minimize MOSFET power dissipation. Output peak
current is 300mA.
The TC170 contains a full array of system-protection
circuits (see Features Section).
Current-mode control lets users parallel power supply
modules. Two or more TC170 controllers can be slaved
together for parallel operation. Circuits can operate
from a master TC170 internal oscillator or an external
system oscillator.
The TC170 operates from an 8V to 16V power supply.
An internal 2%, 5.1V reference minimizes external
component count. The TC170 is pin compatible with
the Unitrode UC1846/UC2846/UC3846 bipolar
controller.
Other advantages inherent in current-mode control
include superior line and load regulation and automatic
symmetry correction in push-pull converters.
