Product specification

Switched-mode power supply control circuit

NE/SE5562

DESCRIPTION

PIN CONFIGURATION

The NE/SE5562 is a single-output control circuit for switched-mode

power supplies. This single monolithic IC contains all control and

protection features needed for full-featured switched-mode power

supplies.

D, F, N Packages

FEED FORWARD

GROUND

OUTPUT

The 100mA source/sink output is designed to drive power FETs

directly. The associated output logic is designed to prevent double

pulsing or cross-conduction current spiking on the output.

DEMAG OVERVOLT IN

EXTERNAL MOD IN

DUTY CYCLE CONTROL

REMOTE ON/OFF

C DELAY

All of the control and protect features work cycle-by-cycle up to the

maximum operating frequency of 600kHz.

OUT INVERT CONTROL

CURRENT SENSE

For ease of interface, all digital inputs are TTL or CMOS compatible.

FEEDBACK VOLTAGE

AUX COMP HYSTERESIS

The NE5562 is supplied in 20-pin glass/ceramic (Cerdip), plastic

DIP, and plastic SO packages. The NE grade part is characterized

and guaranteed over the commercial ambient temperature range of

0°C to +70°C and junction temperature range of 0°C to +85°C. The

SE5562 is supplied in the glass/ceramic (Cerdip) package. The SE

grade part is characterized and guaranteed over the ambient

temperature range of -55 to +125°C and junction temperature range

of -55 to +135°C.
