Maxim’s MAX16936 is a 2,5 A current-mode step-down converter 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 device operates with input voltages from 3,5 V to 36 V, while using only 28 μA quiescent current at no load. The switching frequency is resistor programmable from 220 kHz to 2,2 MHz and can be synchronised to an external clock.
The MAX16936’s output voltage is available as 5 V/3,3 V fixed or adjustable from 1 V to 10 V. The wide input voltage range, along with its ability to operate at 98% duty cycle during under-voltage transients, make the IC well suited for automotive and industrial applications.
Under light-load applications, the FSYNC logic input allows the MAX16936 to either operate in skip mode for reduced current consumption or fixed-frequency FPWM mode to eliminate frequency variation to minimise EMI. Fixed-frequency FPWM mode is very 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 MAX16936s.
The IC operates over the -40°C to +125°C automotive temperature range and is available in 16-pin TSSOP-EP and 5 x 5 mm, 16-pin TQFN-EP packages.
