PIN DESCRIPTIONS  
Pin(S)  
Name  
Description  
Application Information  
Vcc tracks Vin up to 9V. Beyond 9V, Vcc is regulated to 7 Volts.  
A 0.1uF to 1uF ceramic decoupling capacitor is required. An  
external voltage (7.5V – 14V) can be applied to this pin to  
reduce internal power dissipation.  
1
VCC  
Output of the bias regulator  
If the SD pin voltage is below 0.7V the regulator will be in a low  
power state. If the SD pin voltage is between 0.7V and 1.225V  
the regulator will be in standby mode. If the SD pin voltage is  
above 1.225V the regulator will be operational. An external  
voltage divider can be used to set a line undervoltage shutdown  
threshold. If the SD pin is left open circuit, a 5µA pull-up current  
source configures the regulator fully operational.

Input supply voltage  
Nominal operating range: 7V to 42V  
The internal oscillator can be synchronized to an external clock  
with an external pull-down device. Multiple LM25005 devices  
can be synchronized together by connection of their SYNC pins.  
SYNC  
Oscillator synchronization input or output  
The loop compensation network should be connected between  
this pin and the FB pin.

COMP  
FB  
Output of the internal error amplifier  
This pin is connected to the inverting input of the internal error  
amplifier. The regulation threshold is 1.225V.  
Feedback signal from the regulated output  
The internal oscillator is set with a single resistor, connected  
between this pin and the AGND pin. The recommended  
frequency range is 50KHz to 500KHz.  
8
RT  
Internal oscillator frequency set input  
An external capacitor connected between this pin and the AGND  
pin sets the ramp slope used for current mode control.  
Recommended capacitor range 50pF to 2000pF.

RAMP

Internal reference for the regulator control functions  
An external capacitor and an internal 10µA current source set  
the time constant for the rise of the error amp reference. The SS  
pin is held low during standby, Vcc UVLO and thermal  
shutdown.
