Design TPS65263-1Q1
SLVSDY9 – MARCH 2017 TPS65263-1Q1 4.0-to 18-V Input Voltage, 3-A/2-A/2-A Output Current Triple Synchronous
Step-Down Converter With I2C Controlled Dynamic Voltage Scaling
1 Features 3 Description The TPS65263-1Q1 incorporates triple-synchronous
buck converters with 4.0-to 18-V wide input voltage.
The converter with constant frequency peak current
mode is designed to simplify its application while
giving designers options to optimize the system
according to targeted applications. The switching
frequency of the converters is adjustable from 200
kHz to 2.3 MHz with an external resistor. 180В° out-ofphase operation between buck1 and buck2, buck3
(buck2 and buck3 run in phase) minimizes the input
filter requirements. 1 Qualified for Automotive Applications
AEC-Q100 Qualification With the Following
Results:
– Device Temperature Grade 1: –40°C to 125°C
Operating Junction Temperature Range …
