NCP1051 ONSEMI [ON Semiconductor], NCP1051 Datasheet - Page 8

• Manufacturer Part Number: NCP1051
• Description: Monolithic High Voltage Gated Oscillator Power Switching Regulator
• Manufacturer: ONSEMI [ON Semiconductor]

2. Tested junction temperature range for the NCP105X series:
3. Maximum package power dissipation limits must be observed.
4. Guaranteed by design only.
5. Adjust di/dt to reach I
6. Consult factory for additional options including test and trim for output power accuracy.
