Key Featrues
4MHz or 2MHz PWM Switching Frequency - The MAX8640Z operates at up to 4MHz, while the MAX8640Y operates at 2MHz. This high switching frequency allows for the use of tiny external components (1µH inductor and 2.2µF capacitor for the 4MHz version), reducing the overall footprint and making it ideal for space-constrained applications like handheld devices. The optimized frequency also enhances efficiency and minimizes output ripple, ensuring stable performance across varying loads.
Factory-Preset Output Voltages (0.8V to 2.5V) - The device eliminates the need for external feedback components by offering factory-preset output voltages. This simplifies the design process, reduces component count, and ensures precise voltage regulation with ±1% initial accuracy, making it suitable for applications requiring stable power delivery.
500mA Guaranteed Output Current - With a guaranteed output current of 500mA, the MAX8640Y/MAX8640Z can efficiently power a wide range of low-power devices, such as microprocessors, DSP cores, and portable electronics, ensuring reliable performance even under demanding conditions.
Ultrasonic Skip Mode - This feature allows the device to maintain high efficiency at light loads (down to 1mA) by reducing switching losses. It minimizes power consumption in standby or low-power modes, extending battery life in portable applications like cell phones and MP3 players.
Tiny SC70 and µDFN Packages - The compact SC70 and µDFN packages enable integration into space-constrained designs, such as handheld devices and wearables. This small form factor, combined with the ability to use tiny external components, makes it a versatile solution for modern electronics where size and efficiency are critical.
