Maxim Integrated (MAX608ESA+) DC/DC Controller, Boost (Step Up)

DC/DC Controller, Boost (Step Up), 1.8 V to 16.5 V, 1 Output, 300 kHz, NSOIC-8Product OverviewThe MAX608ESA+ is a 5V or adjustable, low voltage, step-up DC-DC controller in 8pin NSOIC package. This BiCMOS, step-up, switch mode power supply controllerprovides a preset 5V output, in addition to adjustable output operation. Itsunique control scheme combines the advantages of pulse frequency modulation (lowsupply current) and pulse width modulation (high efficiency with heavy loads),providing high efficiency over a wide output current range as well as increasedoutput current capability over previous PFM devices. In addition, the externalsense resistor and power transistor allow user to tailor output currentcapability for each application. The device has a shutdown mode that reducessupply current to 5µA max. It is used in high efficiency DC-DC converters,battery-powered applications, positive LCD bias generators and portablecommunicators.Supply voltage range is 1.8V to 16.5VOperating temperature range from -40°C to 85°C85% efficiency for 30mA to 1.5A load currentsUp to 10W output powerMax supply current of 110µAPreset 5V or adjustable output (3V to 16.5V)Current limited PFM control schemeUp to 300KHz switching frequencyBattery-Powered Applications; High-Efficiency DC-DC Converters; PortableCommunicators; Positive LCD-Bias GeneratorsApplicationsPower Management, Portable DevicesProduct InformationSupply Voltage Min: 1.8VSupply Voltage Max: 16.5VNo. of Outputs: 1 OutputController IC Case Style: NSOICNo. of Pins: 8PinsSwitching Frequency: 300kHzTopology: Boost (Step Up)Operating Temperature Min: -40°COperating Temperature Max: 85°CMSL: MSL 1 - Unlimited
