M62290L/FP
5.0 V Fixed Output Voltage DC/DC Converter
REJ03D0850-0300 Rev.3.00 Jun 15, 2007
General Description
The M62290L/FP is a general purpose DC/DC converter which provides 5.0 V fixed output. It is possible to simplify peripheral circuits and to design compact and low cost sets because this IC includes a lot of functions in small 5 or 8-pin packages. Especially this is most suitable for a local voltage regulator of audio sets as a converter from 12 V to 5 V.
Features
* * * * * Wide operation voltage range: 6 to 15 V (typ. VCC = 12 V) Low power dissipation: 1.1 mA (max., VCC = 12 V) Built-in oscillator without peripheral devices (120 kHz typ.) Built-in over current protection circuit Small 5-pin SIP and 8-pin SOP packages
Applications
Local voltage regulator of audio sets and general electric products

Figure 1 Example of Application Circuit of the M62290L/FP * Current limit detection: When the voltage drop between pin 3 and pin 4 becomes more than 140 mV, the current limit detection circuit begins operating. The peak switch current "Ipk" is limited to 140 mV/RCLM. In the example of application (Figure 1), the current is limited to 1.5 A.

Expressions
VO + VF VIN - VCE (sat) - VO 1 fOSC: 120 kHz (VCC = 12 V) fOSC (TON + TOFF) / ( 1 + 1 - TOFF fOSC (VIN - VCE (sat) - VO) x TON (MAX) lO lO + 1 lO 2 TON TOFF )

Note:
VF: Forward voltage drop of an external diode. Vsat: Output saturation voltage of an external switching transistor. IO: Set between 1/3 and 1/5 of the maximum output current. An external transistor, diode and inductor must be have a peak current capability of approximately greater than "Ipk".
