IRU3037/IRU3037A & (PbF)

8-PIN SYNCHRONOUS PWM CONTROLLER

FEATURES

DESCRIPTION

Synchronous Controller in 8-Pin Package

Operating with single 5V or 12V supply voltage

Internal 200KHz Oscillator

The IRU3037 controller IC is designed to provide a low

cost synchronous Buck regulator for on-board DC to DC

converter applications. With the migration of today’s ASIC

products requiring low supply voltages such as 1.8V and

lower, together with currents in excess of 3A, traditional

linear regulators are simply too lossy to be used when

input supply is 5V or even in some cases with 3.3V

input supply. The IRU3037 together with dual N-channel

MOSFETs such as IRF7313, provide a low cost solution

for such applications. This device features an internal

200KHz oscillator (400KHz for "A" version), under-volt-

age lockout for both Vcc and Vc supplies, an external

programmable soft-start function as well as output un-

der-voltage detection that latches off the device when an

output short is detected.

(400KHz for IRU3037A)

Soft-Start Function

Fixed Frequency Voltage Mode

500mA Peak Output Drive Capability

Protects the output when control FET is shorted

SOIC 8-Lead also available LEAD-FREE
