Description



Features:

• Capable of high current drive (IOUT = maximum of 700 mA), using only a few external components
• High efficiency ( = 90% or higher) (@VIN = 5V, VOUT = 3.3V, and IOUT = 300 mA).
• Operating voltage (VIN) range: 3 to 5.5 V
• Low on-resistance (RDS(ON)): 0.27 (typ.) if VIN = 5 V
• High oscillation frequency of 550 kHz (typ.), making it possible to use small external components.
• Uses external phase compensation, assuring a high degree of design freedom in selecting external components and
determining a loop response.
• Employs a current mode architecture with excellent fast load response.
• A small surface mount-type ceramic capacitor can be used as an output smoothing capacitor.
• Housed in a small surface-mount package (PS-8) with a low thermal resistance.
