Unless otherwise specified, the following specifications apply over the operating ambient temperature of -40

°C ≤ TA ≤ 85°C except where otherwise

noted with the following test conditions: VPP= 48V; VEN = HIGH, fs = 250 kHz. Production tests performed at 25°C. Unless otherwise specified VPP is

with respect to VPN_IN, VCC is with respect to PGND.

Notes:

1)

Guaranteed by design

2)

Soft Start Charge Current Equation: Iss_chg = 1.2V/RFREQ

3)

Switching Frequency Equation:

������������������������ =

1

(90������������ ������������������������������)+ 150������������

where Freq is [Hz]

4)

Low Power Mode Clamp Equation: VCLAMP = 0.3 * (RRCLP/RFREQ)

5)

Min and Maximum current are guaranteed by design.
