Product overview
Overview
Description
The FAN5331 is a general purpose, fixed-frequency boost converter designed to operate at high switching frequencies in order to minimize switching noise measured at the battery terminal of hand-held communications equipment. Quiescent current in normal mode of operation as well as in shutdown mode is designed to be minimal in order to extend battery life. Normal mode of operation or shutdown mode can be selected by a logic level shutdown circuitry.
The low ON-resistance of the internal N-channel switch ensures high efficiency and low power dissipation. A cycle-by-cycle current limit circuit keeps the peak current of the switch below a typical value of 1A.
The FAN5331 is available in a 5-lead SOT- 23 package.
Features
• 1.6MHz Switching Frequency
• Low Noise
• Low RDS(ON): 0.5Ω
• Adjustable Output Voltage
• 1A Peak Switch Current
• 1W Output Power Capability
• Low Shutdown Current: <1µA
• Cycle-by-Cycle Current Limit
• Over-Voltage Protection
• Fixed-Frequency PWM Operation
• Internal Compensation
