SWITCHING REGULATOR POWER OUTPUT STAGES

DESCRIPTION

FEATURES

The SM600/601/602 and SM610/611/612 series of Power Output

Stages are especially designed to be driven with standard PWM

integrated circuits to form an efficient switching power supply.

The SM600, SM601 and SM602 are optimized for non-isolated

Buck and Buck-Boost application, where SM610, SM611 and

SM612 are best suited for DC-DC Boost type applications as well

as negative output Buck Converters. The hybrid circuit construc-

tion utilizes thick film resistors on a beryllia substrate for maxi-

mum thermal conductivity and resultant low thermal impedance.

All of the active elements in the hybrid are fully passivated.

• Equivalent to the Unitrode PIC 600, 601, 602, 610, 611,

612

• 5A current capability

• Designed and characterized for switching regulator

applications such as Buck, Boost, and Buck-Boost

type

• Cost saving design reduces size, improves efficiency,

reduces noise and RFI

• High operating efficiency at 2A typical performance -

Rise and fall time < 75ns

Efficiency > 85%

• Electrically isolated, 4-pin, TO-66 hermetic case

HIGH RELIABILITY FEATURES

♦ Available with high reliability processing

)

Note 5. 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 measured, is represenative of typical operating conditions for the SM600 series switching regulators.

Note 6. SM610/611/612 Test Circuit and waveforms are identical but of opposite polarity (V_IN= -25V, V_OUT= -5V, I_DRIVE= +20mA).
