APPLICATION INFORMATION
BOOST CONVERTER
Figure 19. Boost converter block diagram
The boost converter is designed for output voltages up to 18 V with a switch peak current limit of 4 A minimum.
The device, which operates in a current mode scheme with quasi-constant frequency, is externally compensated
for maximum flexibility and stability. The switching frequency is selectable between 630 kHz and 1.2 MHz and
the minimum input voltage is 2.5 V. To limit the inrush current at start-up a soft-start pin is available.
TPS65148 boost converter’s novel topology using adaptive off-time provides superior load and line transient
responses and operates also over a wider range of applications than conventional converters.
