ADP1610

The regulator loop gain is

DIODE SELECTION

The output rectifier conducts the inductor current to the output

capacitor and load while the switch is off. For high efficiency,

minimize the forward voltage drop of the diode. For this reason,

Schottky rectifiers are recommended. However, for high voltage,

high temperature applications, where the Schottky rectifier

reverse leakage current becomes significant and can degrade

efficiency, use an ultrafast junction diode.

A_VL

where:

_VLis the loop gain.

_FBis the feedback regulation voltage, 1.230 V.

_OUTis the regulated output voltage.

_INis the input voltage.

Make sure that the diode is rated to handle the average output

load current. Many diode manufacturers derate the current

capability of the diode as a function of the duty cycle. Verify

that the output diode is rated to handle the average output load

current with the minimum duty cycle. The minimum duty cycle

of the ADP1610 is

_MEAis the error amplifier transconductance gain.

_COMPis the impedance of the series RC network from COMP to

GND.

_CSis the current sense transconductance gain (the inductor

current divided by the voltage at COMP), which is internally set

by the ADP1610.

V_OUT

_OUTis the impedance of the load and output capacitor.

where V_IN-MAXis the maximum input voltage.

To determine the crossover frequency, it is important to note

that, at that frequency, the compensation impedance (Z_COMP) is

dominated by the resistor, and the output impedance (Z_OUT) is

dominated by the impedance of the output capacitor. So, when

solving for the crossover frequency, the equation (by definition

of the crossover frequency) is simplified to

LOOP COMPENSATION

V_OUTV_OUT

2π × f_C×C_OUT

The ADP1610 uses external components to compensate the

regulator loop, allowing optimization of the loop dynamics for a

given application.

where:

f_Cis the crossover frequency.

_COMPis the compensation resistor.

Solving for R_COMP

The step-up converter produces an undesirable right-half plane

zero in the regulation feedback loop. This requires compensat-

ing the regulator such that the crossover frequency occurs well

below the frequency of the right-half plane zero. The right-half

plane zero is determined by the following equation:

2π × f_C×C_OUT×V_OUT×V_OUT

F_Z(RHP) is the right-half plane zero.

Once the compensation resistor is known, set the zero formed

by the compensation capacitor and resistor to one-fourth of the

crossover frequency, or

_LOADis the equivalent load resistance or the output voltage

divided by the load current.

To stabilize the regulator, make sure that the regulator crossover

frequency is less than or equal to one-fifth of the right-half

plane zero and less than or equal to one-fifteenth of the

switching frequency.
