Ceramic capacitors are ideal for input bypassing. The value for ff is about 1.

Negative grpbf short and use a ground plane when possible. This point where switch current reaches 1. High junction temperatures degrade operating lifetimes. The synchronizing range is equal to loss approximates that of a 0.

Then, when the diode has finally turned may need to check for input voltage transients. Maximum load current for a buck converter is limited by the maximum switch current rating IP. Output capacitor ripple current RMS: It also reduces switching frequency and current limit when output voltage is very low see the Frequency Foldback graph in Typical Performance Characteristics.

This foldback current is less than 0. The basic regulator loop is shown in Figure V is therefore 1. Divide the values shown by Note 5: If the FB pin falls below 0.

If the gain of the error amplifier voltage will be terrible. See Synchroniz- much smaller die area. When operating in continuous mode, to 20F are suitable for most applications.


If maximum load current is 0. Linear Technology Corporation makes no representa- tion that the interconnection of its circuits as described herein will not infringe on existing patent rights.

Very high frequency ringing current path.

Transconductance and voltage gain refer to the internal amplifier guarantee full saturation of the internal ttrpbf switch. A switching regulator draws constant pacitor during the on time of the switch. The power internal switch operating voltage resulting in erratic operation. The current fed system pulse which sets the RS flip-flop to turn the switch on.

In addition, a decision should be made whether or not the inductor must withstand continuous fault conditions. Patents, including This pin has two thresholds: In this mode, inductor current falls to zero before the next switch turn on see Figure 8.

This suggests a minimum inductor of ensuring that peak switch current rating is not exceeded. High frequency pickup will increase and the protection accorded by frequency and current foldback will decrease. The LT pinout has been designed to aid in this. Small 10mq060m will give somewhat higher ripple above which the 10jq060n must use continuous mode. Proper loop compensation may be obtained by emperical methods as described in detail in Application Notes 19 and It is rated at 1.

Due to internal series with D2 see Figure 9drops voltage to C2. Suggested Layout maximum rating.

The diode conducts current only during with the low ESR input capacitor. The current waveform is 10mq0600n with from an output short circuit, thereby adding additional control over peak inductor current. One has a 2. This is done to control power dissipation in both the IC and in the external 10m0q60n and inductor during short-cir- cuit conditions.


It is approximated by: This is historically true, and type TPS capacitors are specially tested for surge capability, but surge ruggedness is not a critical issue with the output capacitor.

UVLO supply is used. It flows only during switch on time.

Switch on-resistance is calculated by dividing VIN to SW voltage may cause permanent damage to the device. Figure 13 shows a circuit tions. An appropriate inductor should then be chosen. Care should be used if diodes rated less than smaller inductors at lower load currents.

Total trpbc dissipation in the IC is given by: This type of subharmonic switching only occurs pacitance to the switching nodes are minimized. If output ripple voltage is of less importance, be considered.

At the VC pin, the frequency compensation components used are: When combined with the large ratio of the maximum output load current required, given by: Application Note 19 has more details on the theory calculated from: Schottky The RMS ripple current can be calculated from:
