Operation Description
The JTM1558 adopts fixed frequency, peak current mode boost regulator architecture to regulate output voltage. The
operating principle of the JTM1558 can be easily understood by referring to the functional block diagram. At the
beginning of each oscillator cycle the MOSFET is turned on by the control circuit. To prevent sub-harmonic oscillations at
duty cycle larger than 50 percent, a stabilizing ramp is added to the output of the current sense amplifier and the result is
fed into the negative input of the PWM comparator. When this voltage equals the output voltage of the error amplifier, the
power MOSFET is turned off. The voltage at the output of the error amplifier is an amplified result of the difference
between the 0.6V reference voltage and the feedback voltage. In this way the peak current level keeps the output voltage
in regulation. If the feedback voltage starts to drop, the output of the error amplifier increases, resulting in more current to
flow through the power MOSFET, thus increasing the power delivered to the output. The JTM1558 has internal soft start
to avoid rush input current during the startup and also to avoid overshoot on the output.

Application Information
Because of the high integration in the JTM1558, the application circuit based on this regulator IC is rather simple. Only
input capacitor CIN, output capacitor COUT, inductor L, schottky diode and feedback resistors (R1 and R2) need to be
selected for the targeted applications.
Feedback Resistor Divider R1 and R2:
Choose R1 and R2 to program the proper output voltage. To minimize the power consumption under light loads, it is
desirable to choose large resistance values for both R1 and R2. A value of between 10KΩ and 1MΩ is recommended for
both resistors. If R1=220 KΩ is chosen, then R2 can be calculated to be 30KΩ based on the following equation:
R2 = (R1×0.6V)/(VOUT - 0.6V)
Input Capacitor CIN:
To minimize the potential noise problem, place a typical X5R or better grade ceramic capacitor really close to the IN and
GND pins. Care should be taken to minimize the loop area formed by CIN, and IN/GND pins. In this case a 10uF low
ESR ceramic is recommended.
Output Capacitor COUT:
The output capacitor is selected to meet the output ripple noise requirements. Both steady state ripple and transient
requirements must be taken into consideration when selecting this capacitor. For the best performance, it is recommended
to use X5R or better grade ceramic capacitor with 10V rating and more than two pieces of 22uF Capacitor. The ESR of the
capacitor COUT is critical for low ripple and noise in the output voltage.
Boost Inductor L:
The recommended values of inductor is 2.2uH to 10 u H. Small size and better efficiency are the major concerns for
portable devices. The inductor should have low core loss at 1.2MHz and low DCR for better efficiency. To avoid inductor
saturation current rating should be considered.
Diode Selection:
Schottky diode is a good choice for JTM1558 because of its low forward voltage drop and fast reverses recovery in order
to get better efficiency. The high speed rectification is also a g ood characteristic of Schottky diode for high switching
frequency. The diode reverse breakdown voltage should be larger than the output voltage.
Start-up and Inrush Current:
The JTM1558 has internal soft start to limit the value of current through VIN during the startup and also to avoid
overshoot on the output. The soft start is realized by gradually increasing the output of error amplify during start-up.

备注: | ||||||||||
1. 标注的Id电流是MOS芯片的最大常态电流,实际使用时的最大常态电流还要受封装的最大电流限制。因此客户设计产品时的最大使用电流设定要考虑封装的最大电流限制。建议客户设计产品时的最大使用电流设定更重要的是要考虑MOS的内阻参数。 | ||||||||||
2. 建议在MOS的栅源(G/S)极之间并一个电阻(10K)和一个稳压二极管(5V-12V)起到保护栅源(G/S)极过压的作用。 | ||||||||||
3.建议MOS管的开启电压尽量提高,这样MOS管才能充分开启导通,这个时候内阻最小,不容易发烫。一般建议低压MOS的VGS开启电压设定为4.5V以上,中高压MOS的开启电压设定为10V以上. | ||||||||||
4.MOS 电路操作注意事项: | ||||||||||
静电在很多地方都会产生,采取下面的预防措施,可以有效防止MOS 电路由于受静电放电影响而引起的损坏: | ||||||||||
• 操作人员要通过防静电腕带接地。 | ||||||||||
• 设备外壳必须接地。 | ||||||||||
• 装配过程中使用的工具必须接地。 | ||||||||||
• 必须采用导体包装或抗静电材料包装或运输 | ||||||||||
