The MAX8546EUB+T is a voltage-mode pulse-width-modulated (PWM) step-down DC-DC controller designed for cost-sensitive applications. It supports a wide input voltage range from 2.7V to 28V and can provide output voltages as low as 0.8V, with efficiencies up to 95%.
This controller drives low-cost n-channel MOSFETs and does not require an external current-sense resistor. It includes lossless short-circuit and current-limit protection, with a current-limit threshold of 165mV for the MAX8546. Foldback-current capability minimizes power dissipation under short-circuit conditions. The device operates at a 300kHz switching frequency and is compatible with low-cost aluminum electrolytic capacitors.
Offered in a space-saving 10-pin µMAX package, the MAX8546EUB+T is suitable for surface mount applications. It features input undervoltage lockout and internal soft-start to reduce inrush current. The COMP/EN pin can be used to shut down the device.
Applications include set-top boxes and other cost-sensitive power management needs.
