APPLICATIONS

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 hFE of 400 and VCESAT of 100 mV at IC = 1A. Other
high beta transistors can be used, but the values of RB
and CB may need adjustment if hFE 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 LittlefootTM 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.
