... HA16163T Oscillator The oscillation frequency of the oscillator is set by means of a resistance connected between the RT pin and GND. The following graph shows the relationship between the external resistance and the oscillation frequency. The typical value of the oscillation frequency is given by the following equation. ...

... HA16163T External synchronized operation is possible by supplying a synchronization signal to the SYNC pins of HA16163s. In this case, a frequency not exceeding 1/2 that of the master clock should be set for the HA16163s. A maximum master clock frequency of 4 MHz should be used. See the figure below for the input waveform conditions. ...

... HA16163T • Subinterval turned off at point t1, the primary-side current flows into resonant capacitance Cr2. At this time Cr2 is charged, and therefore the potential of V12 rises. Considering that the exciting current and the L1 and L2 ripple currents are considerable smaller than Io, the following is an approximate equation for the slope of V12. ...

Page 17

... HA16163T • Subinterval turned off at point t3, the primary-side current discharges resonant capacitance Cr1, and the potential of V11 falls. A negative potential is applied to resonant inductor Lr, and a flux reset starts. At this time, since the series resonance circuit is composed of Cr1 and Lr, the V11 waveform changes to a sine wave. The resonance frequency is given by equation (3) ...

... HA16163T • Time: turned on at point t5. The SB switching loss can be minimized by turning on SB when the SB both-side voltages are at a minimum (when the resonance voltage peak). The SB turn-on timing can be set with TD1 of the HA16163. The time when the resonance voltage peak is given by equation (4). ...

... Cref Supplying Power from an External Power Supply It is also possible to use an external source as the power supply for the HA16163T as shown in figure 13. The VREFGOOD circuit controls whether the IC is operating or stopped. The threshold voltage of the VREFGOOD circuit is 4.6 V (typ.) on the rising edge and 4 the falling edge. Since the IC’s characteristics vary with the value of the external voltage, this voltage must be provided by a high-precision 5-V source ...
