CP9743 Datasheet | Ceramate Technical

2-Channel Switching Regulator Controller The CP9743 is a 2-channel switching regulator controller that uses a pulse width modulation (PWM) system. Both channels can be used for DC / DC converter operations including step up, step down, and inverting. Because the IC is pactly packaged, it is best suited for use as a power supply in portable equipment. FApplications DC / DC converters in VCRs, notebook puters, etc. .. FFeatures 1) Built-in reference voltage current (±1%). 2) Timer latch, short-circuit protection circuit is built in. 3) Circuit to prevent malfunction during low input voltage is built in. FAbsolute maximum ratings (Ta = 25_C) 4) Built-in reference voltage (2.505V) output pin. 5) Rest period is adjustable over the whole range of duty ratio. FRemended operating conditions (Ta = 25_) - All specs and applications shown above subject to change without prior notice. 1F-5 NO.66 SEC.2 NAN-KAN RD ., LUCHU , TAOYUAN, TAIWAN Email: server@ceramate..tw Tel:886-3-3214525 Http: .ceramate..tw Page 1 of 5 Rev 1.1 Apr.19, 2004 Fax:886-3-3521052 2-Channel Switching Regulator Controller .. - All specs and applications shown above subject to change without prior notice. 1F-5 NO.66 SEC.2 NAN-KAN RD ., LUCHU , TAOYUAN, TAIWAN Email: server@ceramate..tw Tel:886-3-3214525 Http: .ceramate..tw Page 2 of 5 Rev 1.1 Apr.19, 2004 Fax:886-3-3521052 2-Channel Switching Regulator Controller .. - All specs and applications shown above subject to change without prior notice. 1F-5 NO.66 SEC.2 NAN-KAN RD ., LUCHU , TAOYUAN, TAIWAN Email: server@ceramate..tw Tel:886-3-3214525 Http: .ceramate..tw Page 3 of 5 Rev 1.1 Apr.19, 2004 Fax:886-3-3521052 2-Channel Switching Regulator Controller .. - All specs and applications shown above subject to change without prior notice. 1F-5 NO.66 SEC.2 NAN-KAN RD ., LUCHU , TAOYUAN, TAIWAN Email: server@ceramate..tw Tel:886-3-3214525 Http: .ceramate..tw Page 4 of 5 Rev 1.1 Apr.19, 2004 Fax:886-3-3521052 2-Chan...
