busses 30 The LT3752, LT3752вЂ‘1 and LT3753 are highly integrated, high
performance active clamp forward controllers that minimize external
component count, solution size and cost. Two of these controllers,
the LT3752 and LT3753, are designed for inputs up to 100V, while
the LT3752-1 is designed for applications with input voltages greater
than 100VвЂ”suitable for HV car battery and offline isolated power
supplies, industrial, automotive and military systems. All produce
compact, versatile and efficient solutions for single-IC output power
levels up to 400W. Higher power levels are
supported by stacking converter outputs
in series. See Table 1 (on page 4) for a
feature comparison of these devices.
