Descrizione

Traduzione AI

The MAX17232/MAX17233 offers dual synchronous stepdown DC-DC controllers with integrated MOSFETs. They operates over a 3.5V to 36V input voltage range with 42V input transient protection, and can operate in dropout condition by running at 95% duty cycle. The controllers can generate fixed output voltages of 3.3V/5V, along with the capability to program the output voltage between 1V to 10V. These devices use a current-mode-control architecture. The devices can be operated in pulse-width modulation (PWM) or pulse-frequency modulation (PFM) control schemes. PWM operation provides constant frequency operation at all loads, and is useful in applications sensitive to switching frequency. PFM operation disables negative inductor current and additionally skips pulses at light loads for high efficiency. The low-resistance, on-chip MOSFETs ensure high efficiency at full load and simplify the layout. The devices are available in a 28-pin TQFN-EP package with exposed pad, and are specified for operation over -40°C to +85°C.
