FEATURES  
Two 400mA Step-Down Converters  
DESCRIPTION  
Up to 92% Efficiency  
TPS657051/52 are small power management units  
targeted for embedded camera module or other  
portable low power consumer end equipments. It  
contains two high efficient step down converters, a  
low dropout linear regulator and additional supporting  
functions. The 2.25MHz step-down converter enters a  
low power mode at light load for maximum efficiency  
across the widest possible range of load currents. For  
low noise applications the devices can be forced into  
fixed frequency PWM mode using the MODE pin. The  
device allows the use of small inductors and  
VIN Range for DCDC Converter From 3.3V to 6V  
2.25 MHz Fixed Frequency Operation  
Power Save Mode at Light Load Current  
Output Voltage Accuracy in PWM Mode ±1.5%  
100% Duty Cycle for Lowest Dropout  
180° Out of Phase Operation  
1 General Purpose 200mA LDO  
VIN Range for LDO From 1.7V to 6.0V  
Available in a 16 Ball WCSP With 0.5mm Pitch  
capacitors to achieve  
a
small sized solution.  
TPS657051/52 provides an output current of up to  
400mA on both DCDC converters and integrates one  
200mA LDO with different output settings. The LDO  
operates with an input voltage range between 1.7V  
and 6.0V allowing it to be supplied from the output of  
the step-down converter or directly from the system  
voltage.  
APPLICATIONS  
Digital Cameras  
Portable Media Players  
Handheld Equipment  
VCC  
TPS657051/52  
The TPS657051/52 comes in a small 16-ball wafer  
chip scale package (WCSP) with 0.5mm ball pitch.
