TPS7H500x-SEP Radiation-Tolerant 2-MHz Current Mode  
PWM Controllers in Space Enhanced Plastic  
1 Features  
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  
– TPS7H5005-SEP, TPS7H5006-SEP,  
TPS7H5007-SEP  
•
•
•
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.

– Controlled baseline  
– Au bondwire wnad NiPdAu lead finish  
– Enhanced mold compound for low outgassing  
– One fabrication, assembly, and test site  
– Extended product life cycle  
– Extended product change notification  
– Product traceability
