Product Overview

The MAX17233ETIR+ is a 2.2MHz synchronous dual buck controller with 20µA quiescent current in 28 pin TQFN-EP package. It offers dual synchronous step-down DC to DC controllers with integrated MOSFETs. The device operates over a 3.5V to 36V input voltage range with 42V input transient protection and can operate in dropout condition by running at 98.5% 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. This device uses current mode control architecture and 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 layout.
  • Buck 1 and buck 2 switching (fSW1) frequency of 1MHz to 2.2MHz
  • Eliminates external components and reduces total cost
  • No schottky synchronous operation for high efficiency and reduced cost
  • Simple external RC compensation for stable operation at any output voltage
  • All ceramic capacitor solution, ultra compact layout
  • 180° out of phase operation reduces output ripple and enables cascaded power supplies
  • Reduces number of DC to DC controllers to stock
  • Frequency synchronization input reduces power dissipation
  • 8µA shutdown current and 20µA quiescent current in PFM mode
  • Operating temperature range from -40°C to 85°C
