Single and multi-cell system power boost controllers
The ZXSC100/410/420 are voltage
mode inductive boost controllers
aimed at providing power rails from
battery supplies. The ZXSC410/420
provide any regulated voltage above
V
with a typical line regulation of 1%.
The ZXSC420 option provides an
‘end of regulation’ flag which
uses all available battery energy
before signalling a shutdown.
The ZXSC100 caters for single
cell operation with a guaranteed
start up under full load conditions
down to 1V. All products feature
a programmable peak current to
optimize efficiency and supply
requirements. Maximum output
voltages are limited only by
the rating of the external
switching device.
(1) V M - limited only by voltage rating of external bipolar or MOSFET transistor (V CEO /BV DSS )
