DESCRIPTION
The GS-R4840NV is a negative input, negative
output switching voltage regulator that provides up
to 36W output power without input-output isolation.
The output voltage is programmable by input logic
signals that allow 64 steps (6 bit) of regulated
output, from -22 to -60V.

USER NOTES
Digital Information
The GS-R4840NV accepts 6 bit binary at the data
inputs DB0 to DB5. Data are transferred when CS
is low and during the rising edge of WR signal.
tDS and tDH have to be 100ns and 50ns minimum
respectively (see fig. 1).
