3 Description
•
Radiation hardened:
The
TPS7H500x-SEP
series
(consisting
of
TPS7H5005-SEP, TPS7H5006-SEP, TPS7H5007-
SEP, and TPS7H5008-SEP) is a family of high-
speed, radiation-tolerant, PWM controllers in space
enhanced plastic. The controllers provide a number of
features that are beneficial for the design of DC-DC
converter topologies intended for space applications.
The controllers have a 0.613-V ±1% accurate internal
reference and configurable switching frequency up
to 2 MHz. Each device offers programmable slope
compensation and soft-start.
– SEL, SEB, and SEGR immune to
LET = 43 MeV-cm2/mg
– SET and SEFI characterized up to
LET = 43 MeV-cm2/mg
– TID assured for every wafer lot up to
50 krad(Si)

Input voltage: 4 V to 14 V
0.613-V ±1% voltage reference over temperature,
radiation, and line and load regulation
Switching frequency from 100 kHz to 2 MHz
External clock synchronization capability
Synchronous rectification outputs

The TPS7H500x-SEP series can be driven using
an external clock through the SYNC pin or
by using the internal oscillator at a frequency
programmed by the user. The controller family
offers the user various options for switching outputs,
synchronous rectification capability, dead time (fixed
or configurable), leading edge blank time (fixed or
configurable), and duty cycle limit. Each device in
the TPS7H500x-SEP series has a 24-pin TSSOP
package.
