EL7562C - Preliminary  
Monolithic 2 Amp DC:DC Step-down Regulator  
Features  
General Description  
• Integrated synchronous MOSFETs  
and current mode controller  
• 2A continuous output current  
• Up to 95% efficiency  
• 4.5V to 5.5V input voltage  
• Adjustable output from 1V to 3.8V  
• Cycle-by-cycle current limit  
• Precision reference  
• ±0.5% load and line regulation  
• Adjustable switching frequency to  
1MHz  
• Oscillator synchronization  
possible  
• Internal soft start  
The EL7562C is an integrated, synchronous step-down regulator with  
output voltage adjustable from 1.0V to 3.8V. It is capable of delivering  
2A continuous current at up to 95% efficiency. The EL7562C operates  
at a constant frequency pulse width modulation (PWM) mode, making  
external synchronization possible. Patented on-chip resistorless cur-  
rent sensing enables current mode control, which provides cycle-by-  
cycle current limiting, over-current protection, and excellent step load  
response. The EL7562C is available in a fused-lead 16-pin QSOP  
package. With proper external components, the whole converter fits  
into a less than 0.5 in2 area. The minimal external components and  
small size make this EL7562C ideal for desktop and portable  
applications.  
The EL7562C is specified for operation over the -40°C to +85°C tem-  
perature range.  
• Over temperature protection  
• Under voltage lockout  
• 16-pin QSOP package  
Applications
