TOSHIBA Multi-Chip Module
TB7004FL
Synchronous Buck Converter Module
for High-Current and Low-Voltage Applications
The TB7004FL is a synchronous buck converter (step-down
chopper) module. A DC-DC converter can be formed by combining
the TB7004FL with a PWM control IC, inductors, and input and
output capacitors.
Features
Operating frequency: up to 1 MHz
Incorporates 5-V regulator (output current: 10 mA.)
VCIN undervoltage lockout (UVLO)
In UVLO mode, the GH and GL outputs are set Low and
REG5V is set to 0 V. (The internal voltage regulator is shut down.)
Thermal shutdown (TSD)
Low-side MOSFET gate drive voltage: 5 to 12 V (max 16 V)
The low-side MOSFET gate drive voltage is supplied externally via VGIN.
DISBL# is a digital input and can receive either a 12-V or 5-V logic High signal.
DISBL#: H = Enables the internal circuitry.
L
= Disables the internal circuitry and turns off both the high-side and low-side MOSFETs
(GH
= Low, GL = Low). The internal 5-V regulator remains active.
The PWM input provides for 3-state output control.
H: GH
= H, GL = L
L: GH
= L, GL = H
If the PWM input stays between the rising and falling threshold voltages for the 200-ns hold-off time, the
TB7004FL turns off both the high-side and low-side MOSFETs. Thereafter, setting the PWM input High causes
the TB7004FL to resume normal operation.
The internal dead time control circuitry optimizes the switching of the high-side and low-side MOSFETs.
Incorporates boot switch.
Charge switch for the bootstrap capacitor (The boot switch behaves like a Schottky barrier diode.)
Marking
Care should be taken for static electricity when handling this product since it has a MOS structure.
