TPS6240x-Q1 2.25-MHz 400-mA and 600-mA Dual Step-Down Converter  
1 Features  
3 Description  
The TPS6240x-Q1 family of devices are synchronous  
dual step-down DC-DC converters optimized for  
battery-powered portable applications and automotive  
systems. They provide two independent output  
voltage rails powered by rechargeable batteries or  
standard 3.3-V or 5-V voltage rail.  
1
Qualified for automotive applications  
AEC-Q100 qualified with the following results:  
Device temperature grade 1: –40°C to 125°C  
operating junction temperature range  
Device HBM ESD classification level H2  
Device CDM ESD classification level C4B  
The EasyScale™ serial interface allows output-  
voltages modification during operation. The fixed-  
output-voltage versions, TPS62402-Q1,  
TPS62404-Q1, and TPS62405-Q1 support one-pin-  
controlled simple dynamic voltage scaling for low-  
power processors.  
High efficiency—up to 95%  
VIN Range from 2.5 V to 6 V  
2.25-MHz Fixed-frequency operation  
Output current 400 mA and 600 mA  
Adjustable output voltage from 0.6 V to VIN  
The TPS6240x-Q1 operates at 2.25-MHz fixed  
switching frequency and enters the power-save mode  
operation at light load currents to maintain high  
efficiency over the entire load-current range. For low-  
noise applications, one can force the devices into  
fixed-frequency PWM mode by pulling the  
MODE/DATA pin high. The shutdown mode reduces  
the current consumption to 1.2-μA, typical. The  
devices allow the use of small inductors and  
capacitors to achieve a small solution size.  
Pin selectable output voltage supports simple  
dynamic voltage scaling  
EasyScale™ optional one-pin serial interface  
Power-save mode at light load currents  
180° Out-of-phase operation  
Output-voltage accuracy in PWM mode ±1%  
Typical 32-μA quiescent current for both  
converters
