This register sets the switching frequency of the PWM pins and enables resonant mode. To
enable resonant mode, set these bits to 0x3F (11 1111).

Description
This register sets Δt 1 , which is the delay of the rising edge of OUTA from the start of the
switching cycle, t A . Each LSB corresponds to 5 ns of resolution.

Name
Lowest frequency
R/W
R/W
Description
This register contains the eight MSBs of the 12-bit value of the lowest switching frequency (maxi-
mum switching cycle) limit. This value is always used with the top four bits of Register 0x44,
which contain the four LSBs of the lowest switching frequency limit. Each LSB of the 12-bit
value corresponds to 5 ns of resolution for the switching cycle. For example, if Register 0x42
is set to 0xA0 (160 decimal) and Bits[7:4] of Register 0x44 are set to 0xF (15 decimal), the
maximum switching cycle is (160 × 16 + 15) × 5 ns = 12.875 μs, and the lowest switching
frequency limit is 1/12.875 μs = 77.7 kHz.

time of OUTA)
R/W
R/W
Description
This register sets Δt 2 , which is the difference between the falling edge of OUTA and the mid-
point of the switching cycle, t B . Each LSB corresponds to 5 ns of resolution. When the register
value is from 0x00 to 0x7F, the falling edge of OUTA is trailing t B . When the value is from 0x80
to 0xFF, the falling edge of OUTA is leading t B .
