2.35V to 5.5V, 0.5% Accurate, 1MHz PWM  
Step-Down Controllers with Voltage Margining  
0/MAX1962  
General Description  
Features  
The MAX1960/MAX1961/MAX1962 high-current, high-  
efficiency voltage-mode step-down DC-DC controllers  
operate from a 2.35V to 5.5V input and generate output  
voltages down to 0.8V at up to 20A. An on-chip charge  
pump generates a regulated 5V for MOSFET drive.  
Additionally, adaptive dead-time drivers allow a  
wide variety of MOSFETs to be used without risking  
shoot-through.  
0.5% Accurate Output  
Operates from 2.35V to 5.5V Supply  
Generates Low Output Voltage Down to 0.8V  
On-Chip Charge Pump Provides 5V Gate Drive  
Ceramic or Electrolytic Capacitors  
94% Efficiency  
External Synchronization from 450kHz to 1.2MHz  
500kHz/1MHz Fixed-Frequency PWM Operation  
Fast Transient Response  
Fixed-frequency PWM operation and external synchro-  
nization make these controllers suitable for telecom  
and datacom applications. The operating frequency is  
programmable to either 500kHz or 1MHz, or from  
450kHz to 1.2MHz with an external clock. A clock output  
is provided to synchronize another converter for 180°  
out-of-phase operation. A high closed-loop bandwidth  
provides excellent transient response for applications  
with dynamic loads.  
Two Converters Can Operate 180° Out-of-Phase  
4% Voltage Margining for System Test  
10% Accurate Current Sensing (MAX1962)  
Adaptive Dead Time Prevents Shoot-Through  
Lossless current sensing in the MAX1960 and  
MAX1961 is achieved by monitoring the drain-to-source  
voltage of the low-side external FET. The current limit is  
scalable to accommodate a wide variety of MOSFETs  
and load currents. The MAX1962 has 10% accurate  
sense-resistor-based current limiting.

The MAX1960 and MAX1962 have an adjustable output  
voltage from 0.8V to 4.95V. The MAX1961 and  
MAX1962 have four preset output voltages (1.5V, 1.8V,  
2.5V, and 3.3V) and feature 0.5% voltage accuracy  
over temperature, line, and load variations. The  
MAX1960 and MAX1961 also feature voltage-margining  
control inputs that shift the output voltage up or down  
by 4% for system testing.
