LM2733: Does not operate on a fixed frequency

Part Number: LM2733
Other Parts Discussed in Thread: TPS61175, TPS61170

Dear Sirs

I have a question about the LM2733 (X) DC / DC converter. I made a prototype Boost converter, but it does not produce a continuous PWM waveform with a switching frequency of 1.6MHz. The converter goes into burst mode and I'm in trouble. Please give me some advice.

Input voltage: 9V,

Output voltage: 22V,

Load: 1100Ω

L = 47μH

Please refer to the attached photo.
