Overview
MAX17230/MAX17231 2V–36V, Synchronous Dual Buck Controller with Integrated Boost and 20µA Quiescent Current General Description The MAX17230/MAX17231 offers dual synchronous stepdown DC-DC controllers with integrated MOSFETs and a step-up/boost controller.
They operate over a 3.
5V to 36V input voltage range, and down to 2V with the boost controller active.
The devices 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 current-mode-control architecture and can be operated in the 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...
