• Designed and characterized for switching regulator applications
• Cost saving design reduces size, improves efficiency, reduces noise and RFI
• High operating frequency (to > 100kHz) results in smaller inductor-capacitor filter
and improved power supply response time
• High operating efficiency: Typical 2A circuit performance —
Rise and Fall time <75ns
Efficiency >85%
• No reverse recovery spike generated by commutating diode (See note
• Electrically isolated, 4-Pin, TO-66 hermetic case
DESCRIPTION
ESP Switching Regulator is a unique hybrid
transistor circuit, specifically designed, constructed and spe-
cified for use in high current switching regulator applications.
The designer is thus relieved of one of the most time con-
suming, tedious and critical aspects of switching regulator
design: choosing the appropriate switching transistors and
commutating diode, and empirically determining the optimum
drive and bias conditions:
The PIC600 series switching regulators are designed and char-
acterized to be driven with standard integrated circuit voltage
regulators. They are completely characterized over their entire
operating range of — 55°C to -f 125°C. The devices are enclosed
in a special 4-pin TO-66 package, hermetically sealed for high
reliability. The hybrid circuit construction utilizes thick film
resistors on a beryllia substrate for maximum thermal con-
ductivity and resultant low thermal impedance. All of the
active elements in the hybrid are fully passivated.
Application Notes U-68 and U-76 provide a detailed descrip-
tion of the hybrid circuit and design guidance for specific
circuit applications.

Notts:
1. In switching an inductive load, the current will lead the voltage on turn^on and lag the voltage on turn-off (see Figure 2). Therefore, Voltage
Delay Time (t
DV
) = t
d
+ t
ri
and Current storage Time (t,,) == t,, + t,.
•
2. The efficiency is a measure of internal power losses and is equal to Output Power divided by Input Power. The switching speed circuit of
Figure 1, in which the efficiency is measured, is representative of typical operating conditions for the PIC600 series switching regulators.
3. Pulse test: Duration = 300ms. Duty Cycle €2%.
4. As can be seen from the switching waveforms shown in Figure 2 , no reverse or forward recovery spike is generated by the commutating
diode during switching! This reduces self-generated noise, since no current spike is fed through the (witching regulator. It also ImprovM
efficiency and reliability, since the power switch only carries current during turn-on.
