MAX8569200mA Step-Up Converters in 6-Pin SOT23 and TDFN | Development Boards, Kits, Programmers | 6 | Active | The MAX8569A/MAX8569B low-quiescent-current boost regulators provide up to 200mA at output voltages up to 5.5V from a 1.5V to 5.5V input source. The built-in synchronous rectifier allows for over 90% efficiency while achieving small size and low cost by eliminating the need for an external Schottky diode.The MAX8569A provides an adjustable output while the MAX8569B is fixed at 3.0V or 3.3V. The MAX8569B features a power-on reset output (active-low RST) to signal that the output has reached regulation. All devices connect the battery input to the output during shutdown, allowing the input battery to be used as a backup or real-time clock supply when the converter is off.ApplicationsBattery BackupCordless PhonesDigital CamerasLocal 3.3V to 5V SuppliesMedical Diagnostic EquipmentPC CardsPDAs and Smartphones |

MAX8570High-Efficiency LCD Boost with True Shutdown | Voltage Regulators - DC DC Switching Regulators | 7 | Active | The MAX8570 family of LCD step-up converters uses an internal n-channel switch and an internal p-channel output isolation switch. These converters operate from a 2.7V to 5.5V supply voltage and deliver up to 28V at the output.A unique control scheme provides the highest efficiency over a wide range of load conditions. The internal MOSFET switch reduces external component count and a high switching frequency (up to 800kHz) allows for tiny surface-mount components. Three current-limit options are available. The MAX8570 and MAX8572 use a 110mA current limit to reduce ripple and component size in low-current applications. For high-power requirements, the MAX8574 and MAX8575 use a 500mA current limit and supply up to 20mA at 20V. The MAX8571 and MAX8573 use a 250mA current limit for a compromise between ripple and power. Built-in safety features protect the internal switch and down-stream components from fault conditions.Additional features include a low quiescent current and a True Shutdown™ mode to save power. The MAX8570/MAX8571/MAX8574 allow the user to set the output voltage between 3V and 28V, and the MAX8572/MAX8573/MAX8575 have a preset 15V output. These step-up converters are ideal for small LCD panels with low current requirements, but can also be used in other applications. The MAX8571 evaluation kit is available to help reduce design time.ApplicationsCell Phones/Cordless PhonesHandy TerminalsLCD Bias GeneratorsOrganizersPalmtop ComputersPDAs and Other Handheld DevicesPolymer LEDs (OLED) |
