Product Description

The MAX17503ATP+ is a high efficiency, synchronous step-down DC to DC converter with internal compensation in 20 pin TQFN package. This high voltage converter with dual integrated MOSFETs operates over 4.5V to 60V input. It delivers up to 2.5A and 0.9V to 90%VIN output voltage. The built-in compensation across output voltage range eliminates need for external components. The device has peak current mode control architecture with MODE feature that can be used to operate device in PWM, pulse frequency modulation (PFM) or discontinuous conduction mode (DCM) control schemes. An open-drain active-low RESET pin provides delayed power good signal to system upon achieving successful regulation of output voltage. It is used in distributed supply regulation, base station power supplies, wall transformer regulation, high voltage single board systems and general purpose point of load.
Eliminates external components and reduces total cost
Operating temperature range from -40°C to 125°C
No schottky synchronous operation for high efficiency and reduced cost
Internal compensation for stable operation at any output voltage
All-ceramic capacitor solution, ultra compact layout with as few as eight external components
Input quiescent current of 118µA at VFB = 1V, MODE = RT = open and input shutdown current of 2.8µA
100KHz to 2.2MHz adjustable frequency with external synchronization
Reduces power dissipation and peak efficiency of greater than 90%
Adjustable soft-start and pre-biased power-up
Hicc-up mode current limit, autoretry start-up and output enable/undervoltage lockout
