Figure 4. ZL2004 Block Diagram
The ZL2004 operates as a voltage-mode, synchronous
buck converter with a selectable constant frequency
pulse width modulator (PWM) control scheme that
uses external driver, MOSFETs, capacitors, and an
inductor to perform power conversion.

Dual output PWM ZL2004
The ZL2004 provides a dual PWM signal which
removes the need of a tri-state function and
significantly improves conversion performance.
The ZL2004 has been designed to drive the QH and
QL independently, allowing greater control of the
MOSFETs and higher overall performance. A special

driver with two PWM inputs is required (ZL1505).
Using two PWM signals (PWMH and PWML) offers
more options during fault event and pre-bias
conditions, eliminating the need for a tri-state driver
and reducing the delays associated with this scheme.

converter topology showing the primary power train
components. This converter is also called a step-down
converter, as the output voltage must always be lower
than the input voltage.

The ZL2004 has several features to improve the power
conversion efficiency. A non-linear response (NLR)
loop improves the response time and reduces the
output deviation as a result of a load transient. The
ZL2004 monitors the power converter’s operating
conditions and continuously adjusts the turn-on and
turn-off timing of the high-side and low-side
MOSFETs to optimize the overall efficiency of the
power supply. Adaptive performance optimization
algorithms such as dead-time control, diode emulation,
