W-CDMA/N-CDMA Cellular Phone HBT PA  
Management ICs  
General Description  
Features  
The MAX1958/MAX1959 power amplifier (PA) power-  
management ICs (PMICs) integrate an 800mA, dynami-  
cally adjustable step-down converter, a 5mA Rail-to-  
Rail® operational amplifier (op amp), and a precision  
temperature sensor to power a heterojunction bipolar  
transistor (HBT) PA in W-CDMA and N-CDMA cell  
phones.  
ꢀ Step-Down Converter  
Dynamically Adjustable Output Voltage from  
0.75V to 3.4V (MAX1958)  
Dynamically Adjustable Output Voltage from  
1V to 3.6V (MAX1959)  
800mA Guaranteed Output Current  
130mV IC Dropout at 600mA Load  
Low Quiescent Current  
The high-efficiency, pulse-width modulated (PWM), DC-  
to-DC buck converter is optimized to provide a guaran-  
teed output current of 800mA. The output voltage is  
dynamically controlled to produce any fixed-output volt-  
age in the range of 0.75V to 3.4V (MAX1958) or 1V to  
3.6V (MAX1959), with settling time less than 30µs for a  
full-scale change in voltage and current. The 1MHz PWM  
switching frequency allows the use of small external  
components while pulse-skip mode reduces quiescent  
current to 190µA with light loads. The converter utilizes a  
low on-resistance internal MOSFET switch and synchro-  
nous rectifier to maximize efficiency and minimize  
external component count. The 100% duty-cycle opera-  
tion allows for an IC dropout voltage of only 130mV (typ)  
at 600mA load.  
190µA (typ) in Skip Mode (MAX1958)  
3mA (typ) in PWM Mode  
0.1µA (typ) in Shutdown Mode  
1MHz Fixed-Frequency PWM operation  
16% to 100% Duty-Cycle Operation  
No External Schottky Diode Required  
Soft-Start  
ꢀ Operational Amplifier  
5mA Rail-to-Rail Output  
Active Discharge in Shutdown  
800kHz Gain-Bandwidth Product  
120dB Open-Loop Voltage Gain (R = 100kΩ)  
L
ꢀ Temperature Sensor  
Accurate Sensor -11.7mV/°C Slope  
-40°C to +125°C-Rated Temperature Range  
The micropower op amp is used to provide bias to the  
HBT PA to maximize efficiency. The amplifier features  
active discharge in shutdown for full PA bias control. It  
has 5mA rail-to-rail drive capability, 800kHz gain-band-  
width product, and 120dB open-loop voltage gain.  
ꢀ 20-Pin Thin QFN (5mm ✕ 5mm), 0.8mm Height (max)  
Ordering Information  
The precision temperature sensor measures tempera-  
tures between -40°C to +125°C, with linear tempera-  
ture-to-voltage analog output characteristics.
