The MAX16935/MAX16939 are 3.5A current-mode step-down converters with integrated high-side and low-side MOSFETs designed to operate with an external Schottky diode for better efficiency. The low-side MOSFET enables fixed-frequency forced-PWM (FPWM) operation under light-load applications. The devices operate with input voltages from 3.5V to 36V, while using only 28µA quiescent current at no load. The switching frequency is resistor programmable from 220kHz to 2.2MHz and can be synchronized to an external clock. The devices’ output voltage is available as 3.3V/5V fixed or adjustable from 1V to 10V. The wide input voltage range along with its ability to operate at 98% duty cycle during undervoltage transients make the devices ideal for automotive and industrial applications.
Under light-load applications, the FSYNC logic input allows the devices to either operate in skip mode for reduced current consumption or fixed-frequency FPWM mode to eliminate frequency variation to minimize EMI. Fixed-frequency FPWM mode is extremely useful for power supplies designed for RF transceivers where tight emission control is necessary. Protection features include cycle-by-cycle current limit and thermal shutdown with automatic recovery. Additional features include a power-good monitor to ease power-supply sequencing and a 180° out-of-phase clock output relative to the internal oscillator at SYNCOUT to create cascaded power supplies with multiple devices.
The MAX16935/MAX16939 operate over the -40°C to +125°C automotive temperature range and are available in 16-pin (5mm x 5mm) TQFN-EP and 16-pin TSSOP-EP packages.
