2.2MHz, 2A Buck Converters with an
Integrated High-Side Switch
4
Note 1: 100% tested at +125°C. Limits over temperature are guaranteed by design.
Note 2: Output current may be limited by the power dissipation of the package. See the Power Dissipation section in the Applications
Note 3: SYNC input frequency is equal to the switching frequency.
Note 4: From the SYNC rising edge to SOURCE rising edge.
Note 5: From the rising edge of the SOURCE waveform to the rising edge of the CKO waveform.
Note 6: RESET goes high 200ms after V
