4.5V-60V 2.5A Step-Down DC-DC Converter MAX17503ATP

Semiconductors   Switching Voltage Regulators   Item Number:     1567156598
4.5V-60V 2.5A Step-Down DC-DC Converter MAX17503ATP$5.50
Item Description 
This is a 4.5V-60V, 2.5A, High-Efficiency, Synchronous Step-Down DC-DC Converter With Internal Compensation.

The MAX17503/MAX17503S high-efficiency, high voltage, synchronously rectified step-down converter with dual integrated MOSFETs operates over a 4.5V to 60V input. It delivers up to 2.5A and 0.9V to 90%VIN output voltage. Built-in compensation across the output voltage range eliminates the need for external components. The feedback (FB) regulation accuracy over -40C to +125C is 1.1%. The device is available in a compact (4mm x 4mm) TQFN lead(Pb)-free package with an exposed pad. Simulation models are available.

Absolute Maximum Ratings:

VIN to PGND ............................ -0.3V to +65V
EN/UVLO to SGND ........................ -0.3V to +65V
LX to PGND ............................. -0.3V to (VIN + 0.3V)
BST to PGND ............................ -0.3V to +70V
BST to LX .............................. -0.3V to +6.5V
BST to VCC ............................. -0.3V to +65V
CF, RESET, SS, MODE, SYNC,RT to SGND ... -0.3V to +6.5V
FB to SGND ............................. -0.3V to +1.5V
VCC to SGND ............................ -0.3V to +6.5V
SGND to PGND ........................... -0.3V to +0.3V
LX Total RMS Current ................... 4A
Output Short-Circuit Duration .......... Continuous
Continuous Power Dissipation (TA= +70C) (multilayer board)
   TQFN (derate 30.3mW/C above TA = +70C) ...... 2424.2mW
Junction Temperature ................... +150C
Storage Temperature Range .............. -65C to +160C
Lead Temperature (soldering, 10s) ...... +300C
Soldering Temperature (reflow) ......... +260C
