MC34025 ON Semiconductor, MC34025 Datasheet - Page 2

• Manufacturer Part Number: MC34025
• Description: (MC33025 / MC34025) High Speed Single-Ended PWM Controller
• Manufacturer: ON Semiconductor

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
1. Maximum package power dissipation limits must be observed.
2. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
