It supports low on-duty operation to allow stable output of low voltages when there is a large difference between input and output voltages. It also allows the high switching frequency setting, enabling the downsized peripheral circuits and low-cost configuration. MB39A214A realizes ultra-rapid response and high efficiency with built-in enhanced protection features. It is most suitable for the power supply for ASIC or FPGA core, input/output devices, or memory. FEATURES High efficiency Frequency setting by internal preset function : 310 kHz, 620 kHz, 1 MHz High accuracy reference voltage : ± 0.7% (Ta = + 25 °C) VIN Input voltage range : 6 V to 28 V Output voltage setting range : 0.7 V to 5.3 V Possible to select the automatic PFM/PWM selection mode or PWM-fixed mode PAF frequency limitation function (Prohibit Audio Frequency) : > 30 kHz (Min) Built-in boost diode, external fly-back diode not required Built-in discharge FET Built-in over voltage protection function Built-in under voltage protection function Built-in over temperature protection function Built-in over current limitation function Soft-start circuit without load dependence Current sense resistor not required Built-in synchronous rectification type output steps for N-ch MOS FET Standby current : 0 µA (Typ) Package : TSSOP24 (4.4 mm 6.5 mm 1.2 mm [Max]) APPLICATIONS Digital TV Photocopiers STB BD, DVD players/recorders Projectors etc. |
