FAN6520B Fairchild Semiconductor, FAN6520B Datasheet - Page 5

• Manufacturer Part Number: FAN6520B
• Description: Single Synchronous Buck PWM Controller
• Manufacturer: Fairchild Semiconductor

FAN6520B Rev. 1.0.3
Electrical Specifications
VCC = 5V, and TA = 25°C using circuit in Figure 1 unless otherwise noted. The • denotes specifications which apply
over the full operating temperature range.
Notes:
1. All limits at operating temperature extremes are guaranteed by design, characterization and statistical quality
2. Specifications guaranteed by design/characterization (not production tested).
3. To ensure shutdown, COMP/SD pin should be held below 400mV while sinking 6mA of current.
