APPLICATIONS
4.1
Circuit Examples
Figure 4-1 shows a TC110 operating as a 100kHz
bootstrapped regulator with soft start. This circuit uses
an NPN switching transistor (Zetex FZT690B) that has
an h
FE
of 400 and V
CESAT
of 100 mV at I
C
= 1A. Other
high beta transistors can be used, but the values of R
B
and C
B
may need adjustment if h
FE
is significantly
different from that of the FZT690B.
Figure 4-2 and Figure 4-3 both utilize an N-channel
switching transistor (Silconix Si9410DY). This transistor
is a member of the Littlefoot
TM
family of small outline
MOSFETs. The circuit of Figure 4-2 operates in
bootstrapped mode, while the circuit of Figure 4-3
operates in non-bootstrapped mode.
